The European Council says the UK and other EU countries outside the eurozone will be compensated for any liabilities stemming from the latest EU bailout to Greece. Conservative MPs have been seeking assurances that the UK would not lose out in the event of the EU-wide European Financial Stabilisation Mechanism, to which the UK is party, being used to provide £4.9bn in emergency funding to Athens. In a statement, the Council said it had agreed to amend existing regulations to that effect.

Kent Police has become the fourth police force to confirm that it is investigating claims that the former Prime Minister Sir Edward Heath was involved in sexual abuse.

In a statement, the force told the BBC: "Kent Police has today received a report of a sexual assault having been committed in East Kent in the 1960s. The victim has named Sir Edward Heath in connection with the allegation. Detectives are making initial enquiries, and will obtain a full account from the victim." 

The other forces investigating claims relating to the former Prime Minister are Wiltshire and States of Jersey Police. The BBC understands the Met Police is also investigating the late MP.

Another Labour MP draws attention to Alan Johnson's endorsement of Yvette Cooper - is this an orchestrated attempt to push the "anyone but Corbyn" candidate that some in the party have been calling for?

Peter Carroll, who was special adviser to the Lib Dem Treasury minister Danny Alexander, has told the BBC what it was like for him and the party on election night.

In an interview for the World at One he talks frankly about the "awful pause" before the exit poll was unveiled, showing the party had lost more than 45 of its Westminster seats.

Talking to political correspondent Eleanor Garnier, he said his immediate reaction was "oh no,.... please let that be wrong".

He said the party's defeat was so "painful, public and massive.... it was a bit like a Roman execution in the amphitheatre". 

Danny Alexander lost his seat in the tide of SNP gains in Scotland.

Peter Carroll, who stood for Parliament himself in 2010, is now running a consultancy, but hasn't ruled out a return to the political front line.

The former private secretary to Sir Edward Heath has expressed surprise and shock that the former prime minister is being investigated by three police forces as part of their inquiries into allegations of historic child abuse.

Speaking to the BBC, Robert Vaudry - who worked for Sir Edward from 1988 to 1992 - said, "I spent four years working for Ted and we ran his life like a military campaign. We knew what he was doing every minute of every day through that four year period so to think there were things going on that we weren't aware of, very surprised and shocked, incredulous really." 

Former Home Secretary Alan Johnson has confirmed he is backing Yvette Cooper for the next Labour leader. Writing in the Guardian, external, Mr Johnson said Labour should "end the madness" of the growing support for Jeremy Corbyn and elect Yvette Cooper who has the "experience and inner steel" to succeed as the next Labour leader.

The MP for Hull West and Hessle said: “In my view only Yvette Cooper can unite the party to win again. Those members who can’t give her their first preference should give her their second. After over a century of male leaders we have an election where the most qualified candidate to lead our party back to government happens to be a woman. Let’s end the madness and elect her.”

Labour leadership candidate Jeremy Corbyn has told the BBC the sell-off of RBS shares is "a great mistake" 

Mr Corbyn said, "It's being sold at a loss which is not good, but secondly we took RBS into public ownership because of the way it had been run. I think we should be using RBS as a very important investment tool so that we could assert our public control of it, to ensure they invest in infrastructure and manufacturing rather than the way they do things at the present time."

"The timing is bad from the point of view if you want to get a maximum return. I don't want a maximum return, I want the maximum benefit for the entire economy." 

Mr Corbyn also said he was very concerned that the UK would be extending Tornado aircraft strikes in Iraq for a further year.

"I think further bombing is actually going to inflame the situation, it's going to lead to a lot of civilian casualties and therefore I'm not in favour of continuing the bombing or extending the bombing into Syria. There has to be some process where you bring together a coalition of the neighbouring countries to stop the supply of arms to ISIL, to stop the supply of money to ISIL, and stop the purchasing of oil from ISIL."

Rob MacGregor, who's the national officer for finance at the trade union Unite, has described the government's sell-off of RBS shares as "an utter disgrace".
