Labour leader Jeremy Corbyn will not back a second referendum on the final Brexit deal, his spokesman has said.

There are calls for a new Prison and Courts Bill to be introduced by the next government.

It comes after Commons Leader David Lidington confirmed the bill would be among those that will fall after the decision to call a snap election.

The Bill contained a string of proposed changes, including powers to boost security in jails and crack down on the use of drugs and mobile phones, including those flown in by drones.

Peter Dawson, director of the Prison Reform Trust says the bill was "far from perfect but had achieved cross-party support and contained some valuable measures to make prisons fit for the 21st Century". 

"The next government, whatever its political complexion, should reintroduce a prisons bill as a top priority."

On the prospect of Labour backing a second referendum on the final Brexit deal, a spokeswoman for Mr Corbyn said: "Our position hasn't changed and we have laid out our six tests for any Brexit deal.

"We have consistently demanded a meaningful vote in Parliament and, as the government, will bring the deal we negotiate to Parliament before it is finalised to ensure democratic accountability.

"We will be laying out all our policies, including on Brexit, in further detail in the coming weeks and next month in our manifesto."

Shadow chancellor John McDonnell has refused to rule out the possibility of a second EU referendum under a Labour government.

While campaigning in Lewsey, a ward of Luton, Mr McDonnell was asked by the BBC if Labour would rule out categorically a second referendum on Brexit.

He said: "Our policy position at the moment is that we will hold the government to account.

"We've set out our tests on that. Beyond that our policies will be set out in our manifesto."

He added: "We're making sure that whatever deal is done - hopefully under a Labour government - whatever deal is done it will be to protect our economy and protect jobs." 

Asked if a vote for Labour could be a vote for a second referendum, Mr McDonnell repeated: "Our existing policy is holding this government to account and you'll see further policies within our manifesto across the whole range of issues." 

Conservative Party Chairman Patrick McLoughlin has criticised Labour leader Jeremy Corbyn for refusing to rule out a referendum on the UK's deal with the EU.

He said it would compromise the country's Brexit negotiations.

Mr McLoughlin said it was "more evidence of chaos" from Mr Corbyn and Labour and shows the party "can't provide the strong and stable leadership Britain needs".

Green Party co-leader Jonathan Bartley is also a drummer in blues band The Mustangs.

The band, according to their website, has a tour planned for several dates in May - in the middle of the election campaign.

It looks like it will be a busy month for the politician.

The Commons has just approved a motion to cancel the Manchester Gorton by-election, due to be held on 4 May following the death of the incumbent Labour MP, Sir Gerald Kaufman.

Because of the surprise general election, the current Parliament will be dissolved at 12:01am on 3 May and there will be no sitting Parliament for a winner of the contest to join. Manchester Gorton will instead choose its next MP as part of the general election on 8 June.

Leader of the House David Lidington said cancelling the by-election would avoid "unnecessary expense and uncertainty".

The Green Party has said it may not field parliamentary candidates in some seats in Devon in a tactic calculated to help prevent a Conservative victory.

It suggested it may stand down in Plymouth Sutton and Devonport to give Labour a better chance of winning the seat from the Tory MP Oliver Colville.

In return it wants Labour to agree not to contest the Totnes seat.

Dr Sarah Wollaston, Conservative MP for Totnes described the plans as "anti-democratic".

Prof William Harvey, from the University of Exeter Business School, said: “Jeremy Corbyn is adopting a strategy which risks alienating large and medium-sized businesses which play a vital role in creating employment and wealth for the very people whom he is seeking to serve.

“He is right to require higher levels of transparency, governance and labour practices from these companies, but this needs to be tempered with recognition of their positive impact on the country’s economy and people’s lives – otherwise a large proportion of the electorate will not take him seriously.”

UKIP deputy chair Suzanne Evans says she is "very surprised" that Douglas Carswell has opted to stand down as an MP. 

She told the Daily Politics Mr Carswell’s decision to back the Conservatives in the coming election might be “a little bit premature”, as the UKIP candidate for Clacton has not yet been selected.

Ms Evans is writing the UKIP election manifesto.
