Shadow Cabinet Office minister Jon Trickett says government spending on no-deal preparations is "too little now, because it's too late".

He says preparations have been "inadequate" and caused great uncertainty, adding that the status of UK citizens living in the EU has yet to be resolved.

He criticises the PM's decision to prorogue - or suspend - Parliament from next week, and says plans to push for a general election are "cynical".

The Labour Party would be ready for an election, he adds.

Labour transport secretary Andy McDonald says Boris Johnson is in a "particularly weak position" after his appearance in the Commons.

"We've got a prime minister whose authority is just ebbing away by the hour," he says. "He failed to answer fundamental questions about the progress that he says he's made [in getting a deal]."

He says Mr Johnson's warning of a potential general election was a "mere ruse" and "simply another way of winding the clock down to 31st October".

MPs have finished grilling Boris Johnson after his statement to the Commons. What have we learned so far?

• As the prime minister made his statement, he lost his majority, with a Tory MP crossing the floor of the house to join the Liberal Democrats
• Phillip Lee, the defecting MP, said the Conservatives had become "infected" with "populism and English nationalism"
• It was revealed Mr Johnson will travel to Dublin on Monday, but Irish taoiseach Leo Varadkar said he will "stand firm" over the border issue
• The prime minister said the opposition were demanding he "surrender" control over the negotiations with the EU
• Labour leader Jeremy Corbyn demanded an assurance that Mr Johnson would abide by legislation to block an "undemocratic" no-deal Brexit
• Mr Corbyn said he believes "we have the MPs" to pass legislation to prevent no deal

Michael Gove says Operation Yellowhammer, a government study on no-deal planning leaked over the summer, outlined what a "reasonable worst case scenario might involve".

The document was not a "not a base case scenario" but "what may happen in a worst case scenario", he says, to help the government prepare.

He adds that the government will do "all it can" to help businesses prepare, but adds it is important that firms "familiarise themselves" with what will be required to get ready.

Former Conservative minister Guto Bebb, who plans to rebel tonight, says his colleagues who are thinking of voting against the government are under "immense pressure".

Referencing the prime minister's reported threat to deselect those that vote against him, Mr Bebb says: "In effect, Boris Johnson is threatening them with losing their job, simply for doing what he did numerous times when Theresa May was prime minister, which is to vote against the Conservative whip.

"I think it's quite hypocritical of the prime minister to be perfectly frank."

Mr Bebb says he will rebel because the implications of a no-deal Brexit are "so significant" that he's "duty-bound" to act.

The default position is the UK will leave the EU on 31 October at 23:00 GMT.

The PM says he wants a new deal with the EU on the terms of leaving but has vowed Brexit will happen on 31 October even if that is with no deal.

Michael Gove says the government is "determined" to get a deal and the EU is "moving" because of the PM's determination to deliver Brexit in all circumstances by 31 October.

He calls on MPs to give Boris Johnson the "time and space he needs" to get a good deal.

He says no one should be "blithe or blase" about the challenges required to prepare for a no deal, but adds that "significant challenges can be met".

"We can be ready", he tells MPs.

Lady Hermon, MP for North Down, accuses the prime minister of treating Northern Ireland in a "careless manner", BBC NI political reporter Jayne McCormack says.

The Independent Unionist MP claims the government has asked for legal advice on whether the backstop breaches the Good Friday Agreement and calls on Boris Johnson to make it public.

Labour Brexiter Kate Hoey says there are "many" MPs who "seem to want to stop" the outcome of the 2016 Brexit referendum being implemented.

"Whose side is he on?", she asks.

In reply Boris Johnson says the Commons has promised "many, many times" to honour the result.

"I hope we now get on and do it," he adds.

Labour MP Hilary Benn says there are "a growing number of MPs who have come to the conclusion that what he [Boris Johnson] really wants is a no deal".

"That is why many of us will try to prevent that from happening," he says.

"The sad truth is there are many members in this House who simply want to block Brexit," replies Boris Johnson.

"The last thing we hear about in this place is the democratic will of the 17.4m who voted to leave the EU," says Conservative MP Richard Drax.

The proposed bill "is nothing more than revocation of Article 50," he says. Article 50 sets out what happens when a country decides that it wants to leave the EU.

Mr Drax says the bill would "bind the prime minister's hands to the point we will never leave the EU".

BBC chief political correspondent Vicki Young says the loss of the government's working majority is an "important moment".

But she says it's worth remembering that former Conservative Phillip Lee - who defected to the Lib Dems - hasn't voted with the government on Brexit for a while.

"That working majority has not been realistically working in practice for quite some time," she says.

The Independent Group for Change leader Anna Soubry asks the PM to confirm that Dominic Cummings described the renegotiation as "a sham" - as reported in the Daily Telegraph.

"Could he also tell the House if it is true that he rang the editor of the Daily Telegraph and remonstrated with him about the report," she asks.

"Did you ring him up, yes or no?"

The prime minister says the story seemed to be "wholly implausible".

"I have not seen fit to ring any journalist today on any matter," he says.

Jennie Rigg, chair of the Lib Dems LGBT group, says on Twitter that she has sent an email to the membership resigning after the party accepted Phillip Lee as an MP.

Among her concerns is his support in 2014 for banning HIV-positive immigrants from Britain.

In a blogpost, Ms Rigg accused him of being a "homophobe, a xenophobe, and someone who thinks people should be barred from the country if they are ill".

A bit more on the latest Tory MP to show a lack of support in the prime minister. Former Conservative Phillip Lee, MP for Bracknell, crossed the floor of the Commons to join the Liberal Democrats in dramatic fashion.

The ex-justice minister, who supported Remain in the 2016 EU referendum, has previously warned about the economic impact of Brexit and called for a second referendum on the matter.

Dr Lee lost a vote of no confidence in him by his local Conservative association in June this year - a move "inspired", he said, by his views on Brexit.

He joined the Conservative Party almost 30 years ago and has represented his constituency since 2010.

He is the fourth addition to the Liberal Democrat parliamentary party in the last few months - following in the footsteps of Chuka Umunna, who quit Change UK in June.
