George Osborne says the four largest Greek banks all have branches here, with their deposits totalling less than £255m. He says all branches remain open today. He says there are 40,00 British residents in Greece, whose Greek banks accounts are subject to the capital controls - but not their British accounts. But the situation remains fast-moving and uncertain, and it will be kept under review, he tells MPs.

This Greek crisis has been ongoing for five years and he says the situation today shows it is the biggest external risk to the British economy. "That is why I have consistently argued that the best way to protect ourselves from these risks is to get our own house in order," he tells the Commons.

George Osborne says there is considerable uncertainty about what happens next. Britain's attitude is thus, he tells MPs: Hope for the best but prepare for the worst. On the referendum, called by the Greek government, Mr Osborne says Britain should plan on the assumption that it is a vote on whether the country should stay in or leave the euro.

As David Cameron's statement draws to a close, Speaker John Bercow informs the House that no fewer than 70 backbench MPs were able to question the PM. Time now for the next statement, from Chancellor George Osborne who is updating MPs on the Greek debt crisis.

Sarah Wollaston, the Conservative chair of the Health Select Committee, asks David Cameron if he agrees it is time for the media to review their editorial policies and "stop publishing stills of snuff videos and blasting us with the faces of smirking terrorists". Let's instead see the faces of the Tunisians "who stood arm in arm to protect innocent tourists", she says.

The PM says it is an important point, adding that the media must exercise its own view about "social responsibility" and what it should and shouldn't publish. He repeats his wish for the BBC to stop calling IS Islamic State.

Peter Bone, in a question on the EU, asks why the British media say David Cameron can’t achieve the EU reforms that he’s seeking. He's sure the PM will, he says. Mr Cameron thanks the eurosceptic MP for his support and, in a lighter moment, quips: "I want to continue this ever-closer union between us, for as long as possible.”

Labour MP Heidi Alexander prompts noises of objection on the Tory benches for claiming the UK is not accepting its “fair share” of migrants crossing the Mediterranean for Europe because it thinks “ human suffering is easier to bear if it is just made someone else’s problem”.

Mr Cameron disagrees with her comments, saying Britain is "fulfilling its moral obligations" by rescuing migrants from the Mediterranean.

Ian Paisley, the DUP MP for North Antrim, welcomes the PM's statement and the national one-minute silence that he has announced to mourn the victims of the Tunisia beach attack. He asks David Cameron how much of the aid given to Tunisia is being directed towards the education of people there "away from fundamental beliefs". "Not enough," Mr Cameron tells him, saying it has largely been focusing on building up the Tunisian democracy. "We will have to look again at these partnership programmes," he adds.

Conservative Eurosceptic MP David Nuttall asks his party leader and PM to "pass on my thanks" to fellow European leaders, as "every time" one of them "refuses" one of the PM's "modest requests" on EU reform it makes the Eurosceptics' task of campaigning for Britain to leave the EU "that very little bit easier".

Mr Cameron laughs, before telling his backbencher that he doesn't want to disappoint him but the reception he's been getting in the EU is "more positive than he might suggest".  

Earlier in his statement, the prime minister announced a national minute's silence will be held to remember those who have lost their lives in the Tunisian beach attack. It will take place on Friday 3 July at 12:00 BST, a week after the shooting which killed 38 people.

Strike action in Calais has led to the closure of the port and cancellation of ferry sailings from Dover.

MyFerryLink workers in France have taken industrial action for the second time within a week after its ferries were sold to rival firm DFDS Seaways.

All ferry services between the Port of Dover and Calais, external are affected by the action, although DFDS is still sailing to Dunkirk as normal.

Passengers have been advised to contact ferry operators before travelling.

In response to a question from Jeremy Corbyn, a candidate vying for the Labour leadership, Mr Cameron says: "If he's saying do I regret the action we took to stop Colonel Gaddafi from massacring his own people in Benghazi, no I don't," adding: "The cause of terrorism is people choosing to take up terror."

Bob Stewart, the Conservative MP for Beckenham, sounds a warning about the difficulty for the security services in spotting and preventing lone wolf attacks. Mr Cameron says he is right.

Rushanara Ali says the appalling act of terror on the beach at Sousse last week highlights the need to fight terrorism "at home and abroad". She wants to know what steps the PM will take to ensure the international response also focuses on rebuilding post-conflict states such as Libya. David Cameron says she is right to highlight the need for this.

Keith Vaz, chairman of the Home Affairs Select Committee, welcomes Home Secretary Theresa May's presence in Sousse to "reassure" the British people and also the Tunisian government.  

Meanwhile, Conservative MP John Baron says "we have failed to significantly disrupt" IS's financial flows from Arab-friendly countries, as well as their prominence on social media and business activities. What else can be done, he asks? Mr Cameron doesn't agree with his analysis, saying air strikes in Iraq have shrunk IS' hold on territory in the country. "But we have to demonstrate real, long-term resolve," he adds.
