There is a sense among Tory rebels that they are hardening to fight Boris Johnson tooth and nail.

There was an extraordinary interview with Philip Hammond this morning.

He is a man who is normally considered to be quite dull. Now he has turned into an attack dog.

What is interesting is that there are broader signs in the Conservative Party of real unease at Boris Johnson's strong arm tactics.

What will particularly worry Boris Johnson is that there had been a working assumption that Jeremy Corbyn would back a general election.

I get the distinct feeling that momentum inside the Labour party is against giving Boris Johnson the go ahead for a general election

Why? Because they do not trust him not to change the date of the election to after the 31 October - in other words after we have left the EU without a deal.

A judge in Edinburgh has begun hearing arguments over the prime minister's plan to shut down the UK Parliament.

A cross-party group of parliamentarians wants a ruling at the Court of Session that Boris Johnson is acting illegally.

The UK government is opposing the move, and argues it acted within its powers by seeking to prorogue Parliament.

The prime minister wants to suspend Parliament for five weeks ahead of a Queen's Speech on 14 October.

Downing Street says it is "simply wrong" to suggest that, if MPs approved a general election, the government could or would try to change the date after Parliament had been dissolved.

There have been reports Boris Johnson could postpone an election until after 31 October, the day the UK is due to leave the EU..

And asked about reports, external suggesting senior advisers described EU negotiations as "a sham", the No 10 spokesperson said they have no knowledge of conversations from meetings of the Exit Strategy committee.

The Board of Deputies of British Jews has raised concerns at the possibility of a general election taking place on 14 October - during the festival of Succot.

Religiously-observant Jews cannot vote on this day because activities associated with work - including writing - are banned on major festivals.

The board's vice president Amanda Bowman says tens of thousands of people would not be able to vote in person or participate on the day.

"While we understand that the situation surrounding Brexit means that there is very little flexibility over dates, we have been in touch with the government to explain the concerns and difficulties that our community would face," she says.

"If a general election is held on 14 October, we will be encouraging everyone affected to apply for a postal vote so that their democratic rights are not affected.”

David Landy from in Hendon, north-west London, says: "I am astounded that someone at Number 10 has not got access to a Jewish calendar.

"It is more than a little inconvenient... If I am not able to register for a postal vote in time, I would feel very disenfranchised."

Theresa May's former director of legislative affairs at No 10 has said it was possible the bill MPs want to introduce to Parliament could have a clause "woven into it" to extend Article 50.

Joe Moor, who served former PM Theresa May as director of legislative affairs at No 10, said it was possible that the House of Commons could ask the Queen to intervene to extend the formal process to leave the EU.

"This is a procedure that was used during Theresa May's time in government to request papers on no-deal forecasts and the legal advice made by the attorney general. But it can be used for other things," Mr Moor said.

He said a request for an extension of Article 50 was a "possiblity".

"All options are open to everybody at the moment," he added.

"If we can predict one thing this week it's that every possible convention and rule will be stretched to the absolute limit."

Back in March Conservative MP Sarah Newton resigned from her post as work and pensions minister after voting to delay Brexit in order to avoid a no-deal exit.

However, she says she will not be joining other rebel MPs in today's vote.

In a statement she says she wants to "enable the PM to have the best chance of achieving an ‘amended deal'".

She adds that she believes the PM is "sincere in his desire to leave the EU with a deal".

Sir John Major has been given permission to help anti-Brexit campaigner Gina Miller oppose the decision to suspend Parliament in the courts.

It is not possible to mount a legal challenge to the Queen's approval of the suspension - known as prorogation - which was confirmed last week. But Ms Miller launched a challenge against the advice the Queen's prime minister gave her.

A spokesman for the judiciary said: “The Court has given permission for Sir John Major to intervene in writing in the judicial review brought by Gina Miller with the prime minister as defendant.

"The court will consider in due course Sir John’s application for permission for his counsel to make oral submissions at the hearing.

“Three other applications to intervene in writing on behalf of the Scottish Lord Advocate; the Welsh Government and [shadow attorney general] Shami Chakrabarti have been granted.”

Labour MP Owen Smith says he is still not sure what his party's stance is on holding a potential general election on 14 October.

Labour leader Jeremy Corbyn said on Monday he would be "delighted" to have a poll.

But Mr Smith told the Victoria Derbyshire programme: "We've heard some mixed messages. My view is that we should vote against a general election that is being sold to us by Boris Johnson... who thinks he is playing the entire country for fools."

Meanwhile, the SNP's Pete Wishart said while the priority was to ensure a no-deal Brexit was "off the table", his party would "welcome" a general election.

He said going to the polls could bring the opportunity to remove both Mr Johnson and a no-deal Brexit from the picture.

Tory MP for East Surrey Sam Gyimah has tweeted he will vote against the government to block a no-deal Brexit.

In a video statement the former minister says: "I have no mandate from my constituents for a damaging and disorderly Brexit.

"The bill today gives the prime minister the time to get the deal he says he wants, but if he fails then it will compel him to ask for an extension instead of crashing out without a deal."
