Tonight in the Commons, MPs have voted against Labour's proposals for an independent commission to examine the SNP's plan for full tax-raising and spending powers to be handed to the Scottish Parliament. Scottish Secretary David Mundell told MPs during the committee stage of the Scotland Bill that he did not need a commission to know that full fiscal autonomy would be a "disaster" for Scotland's finances. The government won the vote by 376 votes to 192. 

Tory MP David Davis, a former shadow home secretary, has cautioned the government against extending powers to fight terrorism in the wake of the Tunisia attacks. Speaking to the BBC's Newsnight, he said he would still oppose plans to give the security services additional surveillance powers. He said:

British travellers to Europe via Calais are being urged to seek alternative routes to avoid being delayed by striking ferry workers.

Industrial action by MyFerryLink workers affected cross-channel services earlier when the Port of Calais was forced to close.

Transport Secretary Patrick McLoughlin said he expected disruption to carry on throughout the week.

Those planning to travel to northern France should "look at information on the websites and see if there are alternative routes", he added, suggesting Dunkirk as an option. He said:

It's been day one of Wimbledon today, and while our colleagues at BBC Sport have covered every ace and drop volley, we have taken the opportunity to delve into the archive to find some politicians playing tennis. This could be quite a men's doubles clash.

The Green Party of England and Wales has urged against a "knee-jerk" response to terror attacks, in wake of the three separate attacks last Friday, saying civil liberties must not be sacrificed.

Deputy leader Shahrar Ali described the attacks that took place as “inhumane”, but also warned the government against fast-tracking its data communications bill in response.

It's been a busy political day, with statements from Prime Minister David Cameron and Chancellor George Osborne on the attack in Tunisia and the Greek debt crisis, respectively.Here's recap of the main events:

- David Cameron described the attack as "brutal and sickening"", and confirmed the gunman was thought to have been part of a network inspired by militants from the Islamic State (IS)

- He spoke about what steps needed to be taken in the fight against extremism

- MPs held a minute's silence in memory of those killed in Friday's beach attack. A national minute's silence will be held this Friday at noon.

- The decision made by Director of Public Prosecutions Alison Saunders not to prosecute Greville Janner over historial sex abuse allegations has been reversed

- George Osborne told the Commons there was considerably uncertainty about what would happen next in Greece and that Britain was prepared for the worst.

- But he said Britain was better prepared to deal with any fall out from the crisis than it would have been five years ago.  

- David Cameron said British voters would not accept a "rigid" EU that cannot handle the Greek crisis and the UK's demands for reform

- Shadow health secretary Andy Burnham said a £3,000 donation he received from the Unite union will not fund his Labour leadership campaign.

Diane Abbott, Labour MP and London mayor hopeful, cautions that the coming days will be "very frightening and distressing" for the Greek people - as well as for those with friends and family there. She seeks assurances from the chancellor that whatever the outcome of Saturday's referendum, Greece remains "part of the family of nations" and the UK will do whatever it can to "mitigate" their plight. George Osborne says he has already said "precisely that".

Tory MP Chris Chope says that for Greece to regain its sovereignty and "become once again masters of their own economic destiny", it should be seeking to leave the eurozone and reinstate the Drachma.

George Osborne, the chancellor, says it's for the Greek people to decide. But he adds that the MP's broad observations about the "constraints" of being in the euro "is one of the reasons why he and I both agree Britain was right not to join [the euro] and shouldn't join in the future".

David Cameron’s first priority was to convince people he had a grip of the current crisis –  with staff sent to help victims and their families in Tunisia, RAF planes deployed to take home the deceased, and survivors being helped to return to the UK.

And his attack on ISIL’s "poisonous narrative" was always going to bring plaudits from his fellow politicians. But the political territory then got a bit trickier to negotiate.

His diagnosis of the problem of radicalisation wasn’t controversial but the consensus became strained when the prime minister suggested a cure. He effectively ruled out British "boots on the ground" in Iraq and Syria - but critics argue there should be more air strikes, and more assistance to those fighting ISIL from our own special forces.

He also talked of bringing forward a bill to undermine ISIL’s modern methods of communication.

This has been dubbed a "snooper’s charter" by former shadow home secretary David Davis, amongst others, and they say it isn’t necessary.

David Cameron also promised further measures to tackle radicalisation.

He didn’t, however, repeat his manifesto commitment today to deny those with extremist views access to the internet. Tackling those who don’t condone violence but whose views might influence impressionable young people is likely to raise questions about free speech - not just from political opponents but from some in his own party.  

The UK government would like a "peaceful and less traumatic" solution to the Greek debt crisis, but things have taken "a turn for the worse" after Greece's decision to hold a referendum on the terms of a new bailout deal, says George Osborne.

George Osborne says that five years ago the UK was "less well prepared to deal with shocks from abroad" but is now in a stronger position "as a result of the difficult decisions we've taken".

He says he looks forward to seeing Labour's response to his new Budget, which he will deliver on 8 July.  

Taking aim at the chancellor, Chris Leslie criticises him for making "bogus comparisons between Greece and Britain, which nobody will take seriously", saying it "undermines his position".

Mr Leslie goes on to say that the Greek crisis has been building up over many years, adding that it is imperative for the institutions to continue to seek a negotiation settlement and for the Greek government to deal with questions about reform and governance.

On Saturday, the European Central Bank (ECB) decided not to extend emergency finance to the Greek banks, after the breakdown of talks on giving heavily indebted Greece the last payment of its international bailout.

The current ceiling for the ECB's emergency funding - Emergency Liquidity Assistance (ELA) - is €89bn (£63bn). It is thought that virtually all that money has been disbursed.

Following the ECB announcement, Greece said its banks would remain shut until 6 July. Cash machines are now reopening, but customers can withdraw only limited amounts.

Global stock markets saw big falls on Monday after the weekend's events which saw Greek banks close for a week.  

It is up to shadow chancellor, Chris Leslie, to respond to Mr Osborne's statement on behalf of the Labour Party. He is seeking reassurances about the situation for British citizens living in, or visiting Greece - and those who hold deposits in Greek banks.

On the wider impact on the British economy of the Greek debt crisis, he asks what discussions the Treasury has been having about this and he seeks more detail about what Mr Osborne has done to urge Greek and eurozone ministers to find a solution to the crisis.

The Foreign Office is updating its travel advice to recommend that British tourists travelling to Greece should take sufficient euros to cover them for the duration of their stay, including for emergencies, George Osborne tells MPs.

In his closing remarks, Mr Osborne insists that "Britain is prepared". He tells MPs it is vital that the Greek government now resolves the current uncertainty and ensures economic and financial stability across Europe.
