Defending his record, ex-chancellor says he put significant funding into alternative energy sources when he was in government.

We need a way to make sure our current situation with gas and electricity prices doesn't happen again, Sunak says, and we need more home-grown energy and energy efficiency.

He backs helping people to insulate their homes as a way to mitigate soaring energy prices.

Firstly, Sunak is asked whether he's prepared to explain now how he would help with energy bills?

He says he has set out a clear plan - including direct payments to people struggling with bills through the welfare system.

However, he adds that he can't solve the coming problems with bills for everybody.

Now it's the turn of leadership rival Rishi Sunak to face Laura's questions

Is Liz Truss changing her thoughts on how independent the Bank of England should be?

The Bank also gained independence from the government in 1997 under a new Labour government. The bank has a mandate to keep inflation at 2% - but the cost of living hit 10.1% in July and is set to rise even further.

Ms Truss has previously said: "The best way of dealing with inflation is monetary policy and what I have said is I want to change the Bank of England’s mandate to make sure in the future it matches some of the most effective central banks in the world at controlling inflation.”

But, as the BBC's economics editor Faisal Islam points out, that view seems to have changed in this race.

A change of direction now as we hear in a pre-recorded interview from Olena Zelenska, the wife of the Ukrainian president.

Here’s a quick introduction to our guest.

• Born 16 February 1978 in Kryvyi Rih, a Russian-speaking area of central Ukraine
• Studied architecture at university
• Married Volodymyr Zelensky September 2003
• Has two children – daughter Oleksandra and son Kyrylo
• Became Ukraine’s first lady when her husband was elected Ukraine’s president in 2019

Here’s our news story on the interview, where she tells us that while the war means people in the UK are counting the pennies - in Ukraine they’re counting the casualties.

Liz Truss has answered Laura's questions - but what did she have to say?

• She promised an announcement on energy bills and supply within a week if she wins the leadership tomorrow.
• Within a month, she promised she would produce a full plan on how the government will reduce taxes and find a way out of these problems – but she refused to give details this morning
• On tax, she said cutting taxes will stimulate growth - despite being pushed on how this model has worked in the past - and she insisted she will undo the rise in National Insurance
• And she said having lower corporation tax will attract more business and investment into the UK - putting it up would be "self-defeating", she insisted
• Truss said she would allow fracking for shale gas where there is local support for it and wants to see more solar panels on commercial buildings - but said we shouldn't be putting them on agricultural land
• Quizzed on the NHS, she said she is committed to the current budget for the health service. She pledged lower waiting times for ambulances and emphasised the need for people to get access to GPs.

Liz Truss says the UK "has a serious issue of energy".

"The reality is that we haven't done as much as we should have done as a country to protect our energy security. We've become dependent on the world market," she tells Laura Kuenssberg.

While it is true that the UK doesn't rely heavily on the likes of Russia for supplies of, for example, gas as our graphic shows, the Kremlin's decision to squeeze gas supplies to Europe will have a knock-on effect. Read more here

Sunday with Laura Kuenssberg

So Liz Truss has told Laura Kuenssberg that she will act immediately - within a week - if she wins the Conservative Party leadership election tomorrow to help people with soaring energy bills.

What do the panel - who were listening in from the other side of the studio - think of this?

Emily Thornberry, Labour frontbencher wants to know who will get help from the government - will it be everyone or will it be targeted?

Joe Lycett, comedian quips that Truss was "very clear" and he feels "reassured". Kuenssberg suggests to him that he's being sarcastic.

Cleo Watson, ex-No 10 adviser says I still think the key question - she dodged - is what happens if Putin turns off the gas? We need an answer sooner rather than later.

She adds that Truss has to win over the hearts and minds of people after this campaign.

Liz Truss promises to be clear with the public about the problems that are heading our way in the coming months, adding that she will have to make unpopular decisions.

Britain has been through worse, she says, but we have the attitude and spirit to deal with the challenges ahead.

Asked about the optics of running for leadership now, Laura asks Truss about people poking fun at photos where she has been compared with former Tory PM Margaret Thatcher during the campaign.

Liz Truss says she's focused on the coming job.

"I might not have presented myself in the slickest way," she admits.

"I might've made speeches that some people have taken the mick out of.

"But in every job I've got on with getting the job done."

Questioned about the state of the NHS, Truss says she is completely committed to the current health service budget.

However, she says there are problems on the ground in the health service, including waiting times for ambulances.

She says, under her government, people will see lower waiting times but also emphasises the importance of people getting access to GPs.

It's worth noting that if she becomes PM Truss has pledged to reverse the rise in National Insurance that the government implemented to fund the NHS and social care.

Truss says as well as working with European partners to explore renewable sources of energy - she will allow fracking for shale gas where there is support for it locally.

She says she would like to see more solar panels on warehouses but is against solar farms in fields - she says we should be using the UK's productive land for food.

Liz Truss tells Laura Kuenssberg that she will cut taxes to stimulate growth.

She says that without boosting the economy the UK will not have the money to spend on the NHS.

She's asked about whether that has worked historically, and whether cutting taxes is inflationary - Truss says it's up to the Bank of England to control inflation and she won't tell them what interest rates to set.

Liz Truss is now asked if she is happy that her proposed tax cuts could benefit the wealthiest rather than the poorest. She wants to cut corporation tax.

Truss argues that looking at everything in her proposed tax policy through the lens of redistribution is wrong.

"Growing the economy benefits everybody," she says.

Liz Truss is asked how she will tackle the energy crisis if she becomes PM.

Truss refuses to go into detail on the show and says she will set out her full plan - if she's elected Tory leader and PM - within a week.

Ms Truss says people are struggling with "eye watering" bills.

She promises to act immediately on bills and energy supply.

Those two things go hand in hand, she says.

Next, Ms Truss is asked if she will be giving people money to pay their energy bills.

Ms Truss says the issue is serious. She says her first port of call will be sorting out supply and promising to sort out resources in the North Sea.

Now we come to the interview with Liz Truss.

To begin, the Tory leadership frontrunner is asked if she can believe she could be about to become prime minister

Ms Truss insists she is not complacent about the leadership election result, due in tomorrow, but says she is ready to be prime minister.

The idea of the show it to have more conversations than arguments, says Laura Kuenssberg, and we may have a bit of fun (comedian Joe Lycett is on today's panel).

The big question of the day is what the new leader can do to ease the cost of living crisis.

Cleo Watson, former No 10 aide is on the panel, and says people may have underestimated Liz Truss.

Joe Lycett thinks the summer-long leadership contest does not sit well with a cost of living crisis.

Emily Thornberry - a Labour MP - says Truss is not really into detail - something Laura says she will try to press both leadership contenders on this morning.

The first Sunday with Laura Kuenssberg is on the air, live on BBC One (and being streamed on this page if you click the play button above) from Studio B at New Broadcasting House.

We'll hear from Liz Truss, and later Rishi Sunak, this morning...
