Will David Cameron be able to remain PM, regardless of whether the UK votes to remain in, or to leave, the EU?

On LBC radio, former SNP leader Alex Salmond said Mr Cameron's position was "now untenable". He said Mr Cameron had put a time limit on his own prime ministership and there was now too much “ill feeling” within the Conservative Party for him to stay.

But former cabinet minister Iain Duncan Smith said he believed the prime minister should stay and implement the result of the vote.

“The last thing we need is a kind of a ruction of the whole process of who’s going to lead.”

On the campaign trail in Merthyr Tydfil, Labour peer Lord Hain says he can "feel the support" for people staying in Europe - but he says he is often initially met with scepticism on the doorstep.

He told the BBC people would switch their opinion in the course of the conversation when they realised an "authentic Labour voice" was in front of them, advocating remaining in the EU.

He says every Labour MP - and assembly member, council and activist should be "getting out there on the doorstep and in the high streets" and stressing to voters that the referendum is not a "dogfight" between Conservative leaders: "This is actually about the future of their country". 

He said Jeremy Corbyn needed to lead the campaign along the length and breadth of the country. He says 99% of the Labour Party "enthusiastically" back Remain. The Labour vote will determine the outcome of the referendum, he says.

So, what's been making headlines today?

Justice Minister and Leave campaigner Dominic Raab says German Chancellor Angela Merkel's intervention in the EU referendum debate shows the Remain camp are panicking.

Pointing out that she'd previously said she wouldn't intervene, he argues:

Mr Raab said it would be difficult for Germany if the UK leaves the EU because it would have to pay more in and they would face a greater burden of migrants.

He says the prime minister needs to be honest about the impact of uncontrolled immigration - and praises Jeremy Corbyn and the unions for highlighting the issue.

But he says the Remain camp need to say whether the pressures on social services that come with migration are "a price worth paying."

Plaintive appeals and warnings from pro-European Labour MPs, backed up now by a prominent union leader, that the party must do more to help bring about a vote to remain in the EU have been taken as an implicit rebuke to Jeremy Corbyn.

They are precisely that.

Mutinous grumbling among backbenchers has become part of the background noise to all Labour Party politics at Westminster, constant as the song of crickets on a warm summer evening and so far about as harmless to the leader many of them privately despise.

If this referendum ends in the momentous outcome of a vote to leave - and that is perfectly possible - and Labour MPs at Westminster are left asking themselves and each other who is to blame, many of them will cast wrathful glances in the direction of their leader.

But will their public and private rebukes be fair?

The Electoral Commission says it discovered on Wednesday that a problem with elections software used by a number of local authorities in England and Wales had led to a small number of non-eligible EU citizens mistakenly receiving poll cards and postal votes.

In a letter to David Cameron, Vote Leave heavyweights Iain Duncan Smith and Bernard Jenkin demanded an investigation should take place into the scale of the problem. 

Commission chair Jenny Watson has written to the two Conservative MPs , externalsaying she takes their concerns "seriously". The exact number of voters affected is expected to be known by tomorrow afternoon.

The economic pain of the UK leaving the EU would be widely shared across all income levels, new research suggests.

Analysis by the Centre for Economic Performance (CEP) appears to counter claims by Leave campaigners that the rich will bear the economic brunt of leaving the EU while the poor will be better off.

It instead found both the richest and poorest in society would be squeezed, while the middle classes will be marginally harder hit, facing short-term losses of up to £1,600 per household and a long-run cut of up to £5,550.

CEP director professor John Van Reenen said:

Former Labour chancellor Alistair Darling has defended his decision to share a platform with the Conservatives in the campaign to keep Britain in the EU.

Lord Darling joined forces with Chancellor George Osborne to write an open letter accusing Vote Leave campaigners of coming up with "uncosted and unworkable proposals".

He said:

When asked about Labour focusing its campaign more on immigration, he said:

He urged Leave campaigners to “level with the public - don’t make it up as you go along”, adding that they need to tell the public what will happen if Britain leaves the EU.

More on news that High Street store BHS is to go into liquidation ... Business Minister Anna Soubry says the government "stands ready to support" the company's 11,000 workers whose jobs are at risk.

An error in the electoral software supplied to a number of local authorities may have been responsible for some EU citizens getting polling cards when they are not eligible to vote on 23 June, the BBC has learnt.

In a letter to David Cameron, Vote Leave heavyweights Iain Duncan Smith and Bernard Jenkin demanded an investigation should take place into the scale of the problem.

Now the BBC has seen a letter from the Electoral Commission to regional counting officers explaining what may have happened.

The commission admits that a glitch in a computer system used by some local authorities may have resulted in voters being wrongly registered for the referendum - when they should, in fact, only be eligible for local elections.

The leaked document suggests that those who received a polling card or postal vote in error will now get a letter saying they will not be able to vote.

A spokeswoman for the Electoral Commission says she believes only "small numbers" of voters have been affected.
