In his letter sacking Nadhim Zahawi, PM Rishi Sunak said the Tory chair had committed a "serious breach of the Ministerial Code".

Sunak launched an independent ethics inquiry after it emerged that Zahawi had paid a penalty to HMRC over his taxes when he was chancellor.

That inquiry has concluded and Sunak is sacking Zahawi as a result of its findings.

Full text of the letter to follow.

Nadhim Zahawi has been sacked by PM Rishi Sunak.

Here’s a quick look at Zahawi's life:

• Zahawi was born in Iraq to a Kurdish family. They fled the country for the UK in the early years of Saddam Hussein's regime
• After studying chemical engineering at University College London, he went into business and in 2000 co-founded polling company YouGov
• He has represented the constituency of Stratford-on-Avon since 2010, and became well-known during the coronavirus pandemic as the minister who oversaw the first vaccine rollout- a project widely judged to have been a success
• In September 2021 he became the education secretary in a cabinet reshuffle
• And he replaced Rishi Sunak as chancellor, in July 2022, after Sunak resigned and called onBoris Johnson to stand down as PM. But - just two days into the job - Zahawi joined those publicly urging Johnson to go
• Zahawi ran for the Tory leadership following Johnson’s downfall, but was eliminated early on
• He remained as chancellor for only nine weeks before Liz Truss’s eventual victory in the contest
• Truss gave him a number of junior ministerial roles. Aftershe was ousted as PM amid economic turmoil, and replaced by Sunak, Zahawi was made party chairman in October 2022

Kuenssberg asks why the PM felt that it was OK for Zahawi to stay in post after it emerged he had paid a tax penalty.

Gove says it was important to make sure all the facts were fully investigated rather than rushing to judgement

"Nadhim is a friend of mine so I can't take any joy in the fact that these events have played out today in the way that they have," he says.

He believes Zahawi co-operated fully with the investigation and hid nothing. The prime minister's letter and the decision speaks for itself as to how serious the matter is, Gove says.

Here's a timeline.

• Nadhim Zahawi co-founded YouGov in 2000 - which became a public company in 2005
• Zahawi was chief executive of the polling company until 2010, at which point he was elected for Stratford-upon-Avon at the general election
• He joined Theresa May's government in the 2018 reshuffle as children's minister
• Zahawi became business minister in 2020, under Boris Johnson - and was later given responsibility for delivering the Covid-19 vaccine programme
• On 5 July 2022, Zahawi became chancellor, after the resignation of Rishi Sunak from that role. It was during this period that Zahawi entered into a multi-million pound tax settlement with HMRC - including a penalty
• Zahawi supported Liz Truss in the first Tory leadership contest of 2022, and then backed Rishi Sunak's bid to be leader
• On 25 October 2022 new prime minister Sunak appointed Zahawi as the chairman of the Conservative Party. It is not clear what he knew about Zahawi's tax issues at the time - which Zahawi later described as an error that was"careless and not deliberate"
• On Monday, Sunak announced that he'd asked his independent ethics adviser to look into Zahawi's tax affairs
• Today, he was sacked by PM Rishi Sunak

The BBC's Laura Kuenssberg begins her morning show with an interview with Levelling-up Secretary Michael Gove - she asks him why Nadhim Zahawi has been sacked. Shouldn't he have gone earlier?

Gove says that when facts emerged about Zahawi's tax affairs, Rishi Sunak called for an independent investigation.

He received the conclusion of that investigation this morning, Gove says.

"Immediately on receipt of the letter decided Nadhim could no longer stay in the cabinet," he says.

Nadhim Zahawi, the Conservative party chairman, has been sacked after weeks of pressure over his taxes.

Levelling-up Secretary Michael Gove has arrived at the BBC's New Broadcasting House in central London for Sunday with Laura Kuenssberg.

We'll bring you what he has to say a bit after 9am..

This coming Wednesday, children across England and Wales are set to miss a day of school as teachers belonging to the National Education Union stage their first of seven planned one-day strikes.

The NEU - whose joint general secretary Mary Bousted is on the Kuenssberg panel - is taking strike action as part of a dispute over pay. Teachers had a 5% rise last year, but the union says that with inflation in the UK of around 10%, that constitutes a real-terms pay cut.

As well as 1 February, national strikes are scheduled for 15 and 16 March. There are several regional dates too.

The NEU is the UK's largest education union, and says the strike will affect 23,400 schools in England and Wales.

Education Secretary Gillian Keegan says she plans to meet union leaders later this week.

Head teachers are expected to take "all reasonable steps" to keep schools open for as many pupils as possible during a strike, according to Department for Education guidance, external.

Flawed government guidance on building standards was partly to blame for the Grenfell Tower fire, Housing Secretary Michael Gove says in an interview with the Sunday Times, external.

He believes the system of regulation was "faulty and ambiguous" and not policed properly by the government.

Gove says there was also an "active willingness" on the part of developers to endanger lives for profit.

The government had previously changed the wording of technical advice that had been criticised, for not making it clear that combustible cladding panels should not be used on tall buildings.

In the interview he says he now accepts the guidance was wrong:

"Yes. The government did not think hard enough, or police effectively enough, the whole system of building safety."

The inquiry into the 2017 fire - in which 72 people died - has closed and is expected to report later this year.

The first guest on this morning's Sunday with Laura Kuenssberg is the cabinet minister responsible for the government's levelling up scheme, Michael Gove.

Dozens of schemes across the UK have been awarded funding as part of the government project.

Prime Minister Rishi Sunak says its aim is "to create jobs, drive growth, and make sure that people feel enormous pride in the places that they call home".

But critics say it doesn't make up for the big cuts in local council funding under the Conservatives.

The Levelling Up Fund awarded £1.7bn to projects in October 2021 and another £2.1bn in January 2023.

The North West of England got the most money in both rounds of funding. In the latest round, the South East came second, prompting questions about why it was benefitting.

The government has highlighted funding per head of population. If you look at the funding awards this way, the North of England clearly does better than the South of England.

The BBC’s Reality Check team have analysed the fairness of the project, and asked whether some places have been left behind. You can read their analysis here.

First impressions matter, and the first 100 days for any leader set the terms for success or failure - just ask Liz Truss.

In a few days Rishi Sunak will hit that milestone - so how has he fared?

With time on his hands when he lost last summer's leadership election to Ms Truss, he was more concerned with clocking up a different kind of century - trying out for his local North Yorkshire cricket team.

The team insisted he fight for a place on the pitch.

Sadly for his amateur cricket career, Ms Truss' political operation blew up not long after it began. So instead of going into bat for the Kirby Sigston first XI, he came to the political crease in the middle of economic and political carnage.

It wasn't just the fever dream of Ms Truss' time in office, but the preceding months and months and months of Conservative meltdown that eventually resulted in the removal of Boris Johnson. Prime Minister Sunak's first task was to cool the temperature and prove to the financial markets that Britain was not quickly becoming a basket case.

Mr Sunak put the brakes on that slide to chaos. As one senior MP says: "Stability, calm, competence - that was the obvious necessary task, and he has responded well to that."

His backers underline how that could never be taken for granted after the turmoil of the autumn. But one former minister wonders whether, now stability is back, can Mr Sunak "get things done" and "can he win?".

Links between Boris Johnson and Richard Sharp are under fresh scrutiny again today, following a report that the then-prime minister was told to stop asking the incoming BBC chairman for financial "advice".

Mr Sharp's appointment is under review following successive reports in the Sunday Times that he helped Mr Johnson secure a loan before getting his job. The paper's latest story cites a leaked Cabinet Office memo, external from December 2020. Officials have declined to comment. Both men deny any wrongdoing.

They have separately said that Mr Sharp was not involved in arranging a loan for the then-prime minister, and say that neither man acted with any conflict of interest.

In the wake of the Sunday Times's fresh report, a spokesman for Mr Johnson insisted to the BBC that he had never received or sought financial advice from Mr Sharp.

The BBC chairman has resisted calls to stand down from his job - saying he expects to be exonerated, as he was appointed "on merit".

Sunday with Laura Kuenssberg

​​No single story stands out as a lead for the Sunday papers. The Sunday Times leads on a story about one of our Sunday with Laura Kuenssberg guests - Michael Gove.

The paper says the Housing and Levelling-up Secretary is the first minister to concede that government shares some of the blame for the 2017 Grenfell Tower fire in west London. Gove says government guidance on building materials "allowed unscrupulous people to exploit a broken system". ​​

Elsewhere, the Sunday Telegraph reports that thousands of patients will receive health care via video link. It’s one element of the government’s plans to ease pressure on the NHS in England. Prime Minister Rishi Sunak is due to set out his plan to deal with the crisis in the health service on Monday.

​​The Daily Star Sunday warns that Britain faces a blast of weather from the Arctic - and terms the new weather phenomenon a “dumpin’ donut”.

As well as the main guests, Laura Kuenssberg will be joined by a panel of three key players who bring their own opinions and expertise to bear on the issues of the day and the interviews on the programme.

This week she’s joined by the former EU Brexit negotiator Michel Barnier, joint general secretary of the National Education Union Mary Bousted and the founder and head teacher of London’s Michaela Community School, Katharine Birbalsingh.

There was a time when Michel Barnier was seldom out of the headlines. As the EU’s chief Brexit negotiator he became a household name as the very public face of the union British voters had chosen to leave. Following his time as a leading Eurocrat, Barnier has re-engaged with French politics - at one point being considered the potential centre-right candidate to take on Emmanuel Macron at last year’s presidential election.

Mary Bousted leads the National Education Union - whose members in England and Wales are going on strike this week. Bousted started her career teaching English in secondary schools before going into higher education where she ran teacher-training courses. She was previously general secretary of the Association of Teachers and Lecturers - one of the two unions which merged to form the NEU.

Katharine Birbalsingh is a former chair of the government’s Social Mobility Commission but is best known for being the head teacher and co-founder of Michaela Community Free School in north-west London. Her approach to education - believing in traditional teaching methods and discipline - generates strong reactions from all sides.

Welcome to our live coverage in text and video of this week’s Sunday with Laura Kuenssberg.

With teachers across England and Wales set to strike on Wednesday, and thousands of children told to stay at home, Kuenssberg will hear from Levelling-up Secretary Michael Gove and Labour’s shadow education secretary Bridget Phillipson.

Also on the show is the US ambassador to the UK, Jane Hartley. With the US and UK both pledging modern tanks to help Ukraine defend itself against Russia’s invading forces, will we hear her view on how much more the West can do to support the government of President Volodymyr Zelensky?

All that and more to come when the programme goes on air at 09:00 GMT.
