More messages of praise for Boris Johnson, this time from one of his loyal supporters Priti Patel.

The former home secretary, who earlier in the day was made a dame in the former PM's resignation honours list, described Johnson as a "political titan whose legacy will stand the test of time".

She tweeted: "Boris Johnson has served our country and his constituency with distinction.

"He led world in supporting Ukraine, got Brexit done, and was our most electorally successful prime minister since Margaret Thatcher."

Here's what's happened ahead of Boris Johnson dramatically resigning as an MP this evening.

Johnson was accused of misleading Parliament over parties held in Downing Street while the UK was under Covid restrictions during the pandemic.

During a hearing in March, he said he had misled Parliament over Partygate - but insisted he'd not done that deliberately.

Johnson was in a combative mood for the hearing and said the gatherings were "essential" work events which he believed obeyed the guidelines.

The former prime minister was given the findings of the MP-led investigation on Thursday. A "warning letter" from the committee set out the criticisms it intended to make and evidence supporting them.

If the committee finds he misled Parliament, it could have recommended his suspension from the House of Commons for 10 days or more, possibly leading to a recall vote and a potential by-election in his west London seat.

I understand Boris Johnson did not tell the Tory Party whips he was resigning - which Nadine Dorries said she did when she quit earlier today.

Some Boris Johnson loyalists elected in 2019 are not happy with tonight’s developments.

Workington MP Mark Jenkinson has taken aim at Christian Wakeford - the Labour MP who defected from the Tories amid the fallout over Covid rule-breaking parties.

"You literally owe your seat to him," he writes.

Johnson's resignation tonight has unleashed familiar Tory factions into the open again.

Another unhappy Tory, Brendan Clarke-Smith, tweets: "Tonight we saw the end result of a parliamentary witch-hunt which would put a banana republic to shame."

If you'd thought we'd seen the back of Tory civil war, tonight may have reopened that can of worms.

If you were going to do a word cloud based on Johnson's statement announcing he's quitting Parliament, Committee would be the one which stood out right at the centre.

It's clear the Privileges Committee are firmly in his sights - and at whose door the former prime minister is putting the blame for today's decision to resign as an MP.

If you need a reminder, the committee has been investigating whether he misled MPs over parties in Downing Street while Covid restrictions were in place.

This committee has a Conservative majority, and its membership and remit was voted on and endorsed by the House of Commons.

According to Johnson, the committee are "determined to use the proceedings against me to drive me out of Parliament", and have not produced any evidence he lied to MPs. He insists that in their "heart of hearts" they know he didn't lie, but have "wilfully chosen to ignore the truth".

All eyes are now on members of the Privileges Committee and its chair - veteran Labour MP Harriet Harman - to have their say in the face of these strident allegations made by the former prime minister.

Johnson's resignation problematic for Tories struggling in pollspublished at 21:23 British Summer Time 9 June 2023

Following Boris Johnson’s hugely explosive resignation, will there be a ripple effect across the Conservative Party?

We’ve already seen Nadine Dorries resign today, forcing a by-election in her Mid Bedfordshire constituency, and now we have another by-election in Johnson’s seat of Uxbridge and South Ruislip.

This is clearly problematic for a party struggling in the polls, and in the next few hours or days it will be interesting to see what sort of ripple effect it has among Boris Johnson’s supporters within the party.

There are a lot of rumours flying about - and we are not in the business of rumours.

But I do check them out.

So are Dame Priti Patel and Sir Simon Clarke about to resign too?

I have been in touch with both.

They both say no.

We've just had some reaction from Boris Johnson's local Conservative association chairman, who says the former PM "has delivered on his promises to local residents".

Richard Mills says: "Contrary to external perception, his commitment to the constituency over the last eight years has been outstanding."

The Uxbridge and South Ruislip Conservative Association chair also praises Johnson for being the "driving force" behind a new Hillingdon Hospital as well as "protecting" Uxbridge police station.

The SNP's deputy Westminster leader, Mhairi Black, says Johnson "jumped before he was pushed".

"No one in Scotland will be sorry to see the back of him but he has also underlined the weakness of Rishi Sunak, who has no authority over the bitterly divided Tory Party," says the MP for Paisley and Renfrewshire South.

We've just had some reaction from Labour, with the party's Deputy Leader Angela Rayner saying the British public is "sick to the back teeth of this never-ending Tory soap opera played out at their expense".

"After 13 years of Conservative chaos, enough is enough," she says.

She adds that it is time to "turn the page" with a Labour government "focused on the people's priorities".

Just a few hours ago former minister Nadine Dorries also announced she was standing down as a Conservative MP with immediate effect.

The close ally of Boris Johnson told TalkTV "something significant" had happened to change her mind but wouldn't give any further details.

That's led to speculation that she could have stood down to let Johnson stand in her much safer seat of Mid Bedfordshire, which has a majority of 24,664.

However, a Conservative party headquarters (CCHQ) source suggests to our political editor Chris Mason the party would prefer a "local" candidate for Mid Bedfordshire.

"The clear implication is they wouldn’t regard west London as ‘local'," he adds.

Johnson's current seat is Uxbridge and South Ruislip in west London, where he has a majority of 7,210.

Boris Johnson is leaving Parliament... for nowpublished at 20:40 British Summer Time 9 June 2023

Boris Johnson is a regular deliverer of political asteroids. Tonight, another one crashes in.

Not only is Boris Johnson giving up as an MP - triggering a by election in a marginal seat.

He is doing so in an explosive manner - taking a direct pot shot at Prime Minister Rishi Sunak as he does so.

Hours after stepping off a plane from Washington in which Sunak transparently wasn’t talking about a free trade agreement with the US (he was never going to be), Johnson says he should have been.

He claims the Commons Privileges Committee is a "kangaroo court".

And he is rallying the Brexit troops in suggesting his demise is driven by a motivation to overturn the result of the EU referendum.

Oh, and anyone thinking Boris Johnson is about to retreat into obscurity, note how his statement ends.

He is leaving Parliament "for now".

Boris Johnson's statement in which he sets out why he is quitting Parliament and rails against the investigation into him clocks in at just over 1,000 words.

We're currently picking out the key bits on this page, but you can read his statement here in full.

We're still picking through Boris Johnson's incredibly long resignation statement.

Taking aim at the Privileges Committee, who are investigating whether he misled MPs over Partygate, the former prime minister said: "I did not lie, and I believe that in their hearts the committee know it."

"They know perfectly well that when I spoke in the Commons I was saying what I believed sincerely to be true and what I had been briefed to say, like any other minister," he said.

Johnson said he corrected the record as soon as possible, and said committee members "know that".

Of course we're only getting Johnson's side of the story at the moment - we're chasing reaction from MPs and will bring you their response as soon as we get it.

Johnson’s resignation comes the day after he received the findings of the Privileges Committee, the MP-led investigation into whether he misled Parliament over gatherings at No 10 Downing Street during the Covid lockdowns.

In evidence given in March, Johnson admitted misleading Parliament, but denied doing it on purpose.

As we reported yesterday, Johnson was sent a “warning letter” by the committee, detailing the criticisms it intended to make of him, as well as any evidence it had.

He was given two weeks to reply to the letter.

Reacting to the news of Boris Johnson's resignation, Liberal Democrat deputy leader Daisy Cooper says simply: "Good riddance."

Boris Johnson's resignation triggers a by-election in his west London seat of Uxbridge and South Ruislip.

He has a majority of 7,210, with Labour coming second in the 2019 general election.

Labour had hoped a strong performance at the next general election could turn the seat red - but now it looks like they will get a crack at taking the constituency sooner than that.

Johnson goes nuclearpublished at 20:33 British Summer Time 9 June 2023

Boris Johnson goes as an MP and goes nuclear.

He and Nadine Dorries are giving ⁦Rishi Sunak unwelcome by-elections and in his statement he suggests that the Conservatives have lost their mojo and abandoned key policies from tax to housing.

Boris Johnson’s resignation comes only hours after he gave some of his closest allies – including Priti Patel and Jacob Rees-Mogg – peerages in his honour’s list.

The long-awaited list, approved nine months after Johnson resigned as prime minister, included 38 honours and seven peerages.

Among the big names were Leader of the Commons Jacob Rees-Mogg, who was knighted, and former Home Secretary Priti Patel, who was made a dame.
