The World Trade Organisation's former director-general tells the BBC that the UK economy risks a "huge blow" if it votes to leave the EU on 23 June.

Senior Labour backbencher Frank Field says parliament should move north during renovations - and maybe stay there. He said that cities like Manchester and Leeds should be putting in a joint bid to say "we'll look after you". He told the Westminster Hour that would break London's "stranglehold" and have "a huge affect on whether we came back again".

Frank Field says the Leave Campaign has made its "first mistake" by questioning David Cameron's integrity in the EU referendum. He told the Westminster Hour that it was a "mistake [for Leave] to put sticky fingers into people's souls" and that it should instead "concentrate on issues and not the integrity of the other side".

Danny Finkelstein says Conservative MPs should "think twice" about a letter-writing campaign against David Cameron. The Conservative peer and Times columnist told the Westminster Hour that MPs would "not struggle" to get 50 names asking for a vote of no-confidence but would fail to remove the Prime Minister, strengthening his position.

• Leading Vote Leave campaigners Boris Johnson and Michael Gove have written a public letter urging David Cameron to accept the failure of the government's manifesto pledge to reduce migration into the UK
• Net migration stands at about 330,000 - well above the target of reducing it to the "tens of thousands"
• Mr Johnson and Mr Gove said the pledge was "corrosive of public trust" while Britain remained in the EU
• But Downing Street said their claim was an "attempt to distract" from the fact that an EU exit would be "disastrous"
• As the Tory infighting intensified, backbench MPs Andrew Bridgen and Nadine Dorries – who want the UK to leave the EU – threatened a Tory leadership challenge after the June referendum if Remain wins by a narrow margin

• Mr Bridgen said up to 50 MPs were prepared to push for a no confidence vote in David Cameron
• But pro-Leave cabinet minister Chris Grayling said such a move would not have the 50 signatures needed to trigger a contest
• Former Tory cabinet ministers Liam Fox and Iain Duncan Smith - both on the Leave side - also played down the prospect of a coup and said the PM would have their backing
• Meanwhile, ex-Labour PM Tony Blair warned against an EU exit, saying it would not solve migration problems and would create an "enormous economic problem" which would affect jobs and living standards
• And an online survey of economists for The Observer showed 88% of those who responded believed that EU withdrawal would be damaging for the UK economy

Boris Johnson and Michael Gove's public letter to David Cameron was also signed by the Labour MP Gisela Stuart, who co-chairs the Vote Leave campaign.

She said the PM should be forced to admit what the consequences of a vote to remain would be.

Lord Neill of Bladen has died, his family has confirmed.

The crossbench peer joined the House of Lords in 1997 but his membership ceased earlier this year due to non-attendance.

The former vice-chancellor of Oxford University was 89.

Earlier, Vince Cable told Sky News the Lib Dems had, in coalition, warned the Tories their net migration target was undeliverable.

Responding to his comments, Vote Leave chief executive Matthew Elliott said Mr Cable had admitted that the UK "cannot control immigration if we stay in the European Union".

He added:

The Leave campaign say this spat is about the UK's ability to limit EU immigration.

But the sight of two senior conservatives - Boris Johnson and Michael Gove - accusing the prime minister, in such a public way, of undermining the trust that voters place in politicians has made this debate deeply personal.

And the in-fighting hasn't stopped there.

The employment minister, Priti Patel, has gone a step further in her criticism - suggesting that Mr Cameron is too rich to care about people's concerns regarding migration.

All of this appears to have unleashed the wrath of Eurosceptic backbenchers.

Leave campaigner Nadine Dorries called Mr Cameron an "outright liar" and said a letter was being circulated among backbenchers calling for a vote of no confidence in the prime minister who she warned would be "toast within days" after the referendum even if Remain narrowly won.

No 10 said the Leave campaign was just trying to focus attention away from the economic debate which it claimed Leave had already lost.

Jeremy Corbyn has added to speculation that he wants Ed Miliband in his shadow cabinet.

Asked on 5 live's Pienaar's Politics earlier if he wanted the former leader - whom he's been on the EU referendum campaign trail with - in his shadow cabinet, Mr Corbyn did not rule out the possibility.

"That is all for the future," he said.

And he defended Mr Miliband over the party's defeat at last year's general election.

Glastonbury founder Michael Eavis has urged festival-goers to vote in the EU referendum, which coincides with the music event.

Former Labour leader Neil Kinnock has expressed some concern about the clash, saying it would be a shame if young people were "rocking instead of voting", according to The Observer.

Mr Eavis, who backs a Remain vote, told the newspaper:

Welsh First Minister Carwyn Jones has said there is still a chance of saving jobs at the Port Talbot steel works.

He said he'd been in Mumbai on Wednesday and there were seven bidders potentially interested in buying all of Tata's assets in the UK. 

But Mr Jones said no one would want to buy these plants if the pension fund was still there.

He also said the outcome of the EU referendum had a potential to "scupper" a sale, saying "all these buyers are holding off to see what the result is on the 23 of June and I've no doubt they'll run if they find the UK has left".

Responding to Tony Blair's comments on immigration in his interview on the Marr Show this morning, Leave campaigner and employment minister Priti Patel said:

Ms Patel also said the former PM had "in effect admitted that he would not support the UK joining the EU as it is today".

Sky News

Former Lib Dem Business Secretary Vince Cable said the party argued throughout the coalition government that the pledge to get immigration below 100,000 was "foolish" and should be dropped.

Mr Cable said that while he agreed in principle with cabinet minister Michael Gove that the target was "unachievable" he didn't recall the Tory minister saying that during the election campaign.

He also said there had been some exaggeration on both sides of the EU referendum during the campaign and that he didn't think the UK would "get armageddon either way".

Mr Cable added that he thought the economic argument had been largely won by Remain.

An SNP MP has spoken out about the sexist and racist abuse she has received since being elected to Parliament last May.

Tasmina Ahmed-Sheikh, who represents the Ochil and South Perthshire constituency, said she had passed more than 100 files of online abuse to police.

The MP told the Sunday Mail newspaper that much of the abuse related to her appearance, or the fact she is a woman and she has also been targeted by Islamic extremists.

Former Defence Secretary and Vote Leave supporter Liam Fox says the Conservatives cannot fulfil their manifesto pledge to reduce net migration to the UK to below 100,000 if the UK stays in the EU.
