Boris Johnson will face a torrent of vitriol and questions about his own response to the dramatic judgement from the Supreme Court.

In public so far Mr Johnson has said he strongly disagrees with the verdict but that he will respect it.

But I think he will really be under the cosh on the strategy he has chosen to take.

Will he change it?

Everything we have seen from this prime minister so far suggests he thinks attack is the best form of defence.

He could now say: “If you don’t like it, have the guts to go to the country.”

But opposition parties are not going to budge on their demand to make it as watertight as possible that we do not leave the EU without a deal before they agree to an election.

This may be a Parliament that cannot agree on anything, but while this happens it is a government that cannot govern properly either.

Ms Thornberry calls for a deescalation of tensions by getting the Iran nuclear deal back on track.

She says that "in an era when we can no longer rely on the United States to provide any global leadership in matters of peace and war", the EU and UN must be clear that it "will not let the nuclear deal be thrown away".

She called US President Donald Trump a "power-crazed president in the White House who wants to start wars rather than end them".

And the shadow foreign secretary added that "real security comes from international cooperation and diplomacy" - rather than military intervention with no planning of what comes next.

Labour MP Hilary Benn, chair of the Commons Brexit committee, tells the BBC that the prime minister has "lost control of events".

"He’s making a terrible mess of being prime minister of the country. He’s losing all of the important votes, he doesn’t have a plan, he doesn’t have a mandate, he doesn’t have credibility, he's thrown away his majority" - all in addition to the Supreme Court defeat, Mr Benn says.

He says Mr Johnson's refusal to accept the court's verdict "doesn't fill us with confidence" that the prime minister will follow his legal obligation to ask for a Brexit extension if he fails to agree a deal by 19 October.

Mr Benn says MPs will have to decide how to make Brexit end, and his preferred option is to go back to the British people in another referendum "to resolve the nightmare".

There was some speculation today that the government might have been preparing to put forward a motion - again - for another general election.

It came after Attorney General Geoffrey Cox earlier told MPs that an election motion would be "coming before the House shortly".

But, according to the Sun's political editor, Tom Newton Dunn, the government won't be putting forward such a vote at the moment.

Labour's shadow foreign secretary Emily Thornberry begins by apologising to her Liberal Democrat colleagues for her "crass, throwaway Taliban remark in an interview last week".

She was referencing comments she made to PoliticsHome comparing the party to the militant group over its plan to stop Brexit without another referendum.

Turning round to face the Lib Dems, she says: "I'm sorry for what I've said.

"I believe politics is better when we can be honest and apologise for our mistakes.

"A lesson that our country's prime minister would be well placed to learn."

Dominic Raab is now making a statement on Iran. This is the last topic before Boris Johnson's update to MPs, which is up next.

Mr Raab says the government is clear that the evidence shows Iran was responsible for the attacks earlier this month on Saudi oil installations.

He also condemns Iran's "dire human rights record", as well as the country's "arbitrary detention of dual-nationals".

"Even now, we retain the hope that we can work with Iran to de-escalate tensions," he adds.

The British Retail Consortium has responded to Michael Gove's claim that the retail sector told him they were ready for a no-deal Brexit.

“We have been crystal clear that while retailers are doing everything they can to prepare for a no deal Brexit on October 31st, there are limits to what can be done," it said in a statement., external

"It is impossible to completely mitigate the significant disruption which would be caused by no deal.

“Checks and delays at the border, limited warehousing capacity in the run-up to Black Friday and Christmas, and the increased reliance on imported fruit and vegetables through the winter months mean that popular goods, such as strawberries, tomatoes and lettuce, would likely see reduced availability, and higher prices.”

Earlier, Attorney General Geoffrey Cox dared the opposition parties to call a general election by passing a "one-line bill" setting the date.

Now, it seems they are preparing what to do if the government introduces a bill like this.

The key issue for them is whether they could amend it to ensure that it doesn't allow a no-deal Brexit to take place during the campaign or the change of government, says BBC political correspondent Nick Eardley.

Two meetings of the 1922 Committee - the group of backbench Conservative MPs - are planned over the next 24 hours.

There's a meeting tonight and also one tomorrow.

According to the Press Association, Boris Johnson is expected to address the committee meeting on Thursday morning.

Maintaining that committee's support is seen as vital for any Conservative Party leader.

BBC News political reporter Jessica Parker adds:

Conservative MP and ex-Cabinet minister Sir John Redwood says a general election is now needed.

"I didn't want an early general election, nor did Boris Johnson when he stood to become leader, but I think now that the government cannot govern and is being taken hostage by the opposition forces who wish to remain in the European Union, we do need a general election to clear the air."

The pro-Brexit MP adds: "I think the British people would be sensible and they would want to have a government that can govern, and only they can decide who that should be."

Earlier, Tory MP Tobias Ellwood - who has called for MPs to compromise - suggested the doors to the chamber should be locked until MPs vote to leave the EU with a deal.

"The Speaker has agreed for refreshments and sleeping bags to be made available in the lobbies," Mr Ellwood writes on his order paper.

One MP, Simon Hoare, says it "has my support".

Get out your diary! If you are as much of a nerd as me.

Watching the two sides in Parliament tear each other to shreds this afternoon, it seems impossible to imagine them ever, ever, agreeing anything again.

The noisiest voices on both sides seem, at the moment, more interested in using every twist and turn to confirm their own views than hunting for a basis for resolving things together.

But let's for a second contemplate that they can.

And imagine that Boris Johnson is willing to compromise, and manages to persuade his counterparts in the EU to budge enough to allow him to strike an exit deal.

What would they do then?

Remember the PM's main priority is to stick to his Halloween deadline for Brexit.

But Parliament has changed the law to force him to ask for a delay if a deal hasn't been done and dusted by the end of the 19 October.

Labour MP Mary Creagh asks about the government's £100m "Get ready for Brexit" campaign.

She calls it a "party political drum beat to the general election", which the PM has twice failed to gain support for.

She references a Buzzfeed article that highlights the data being collected through the campaign.

"When was it decided to collect that data? By whom?", she asks.

"And what help is he giving to the information commissioner who, at my request, is investigating?"

Mr Gove says civil servants have done an "absolutely wonderful job in making sure we provide information to people through the campaign".

He says "many more businesses" are "better prepared" because of it.

He says the data collected "is used in a way to better serve our citizens" - to shouts of "rubbish" in the chamber.

Reality Check

Earlier, Michael Gove told MPs the Brexit negotiations have seen progress - for example, the EU had initially maintained the withdrawal agreement was sacrosanct but has recently acknowledged it can be changed.

Is he right? BBC Reality Check's Chris Morris says "there's some truth in that".

He says now, "slowly, slowly, at technical level mostly", the EU is at least exploring which parts potentially could be changed.

But he adds: "Where I'm not sure that he's right is the idea that they said the backstop can go."

There still needs to be a legally sound solution which replicates all of the elements of the backstop, and that's still the EU's key point, he says.

"The big task for negotiators, and we're a long, long way from this at the moment judging on what we're being told from both sides, is to find something that replaces everything the backstop does."

Joe Twyman, director of the polling group Deltapoll, says the most recent snap polls suggest around half of people believe the Supreme Court's decision was correct, while between 20-25% believe it was wrong.

"But that result corresponds very closely to whether you're a Remainer or a Leaver, whether you voted Conservative or whether you voted for one of the other parties.

"I think people aren't actually paying that much attention to the detail, they're just responding in general terms."

But Mr Twyman adds that the questions being raised over Boris Johnson's relationship with a US businesswoman, following claims he failed to declare a potential conflict of interest when he was London mayor, could have a larger impact on voting.

"It's an easier issue for people to understand," he adds.
