David Cameron's EU negotiations have dominated the political news today - and they also featured in Labour's opposition day debate about tax avoidance in the Commons earlier.

Shadow chancellor John McDonnell said George Osborne should have used the talks to push for a new agreement to tackle avoidance.

Mr McDonnell said Google's £130m tax repayment had "driven a coach and horses" through the chancellor's attempts to change international rules and get multinationals paying more tax.

Treasury Minister David Gauke said Mr McDonnell showed a "complete misunderstanding" of corporation tax.

After a debate, Labour's motion calling for the government to "publish the full details" of their tax agreement with Google was defeated by 271 votes to 299, and a government amendment noting efforts to "clamp down" on tax avoidance passed by 303 votes to 261.

The Schengen Agreement is not dead but it needs to be "rescued" if it is going to continue, the prime minister of Norway, Erna Solberg has told BBC HARDtalk. 

"We need to have a system of redistribution and common solidarity on the amount of refugees that come," she said. 

The EU had started off handling the crisis well, but it was not implementing the decisions that had already been made, she added.

The Leave.EU campaign says the departures of Dominic Cummings and Matthew Elliott from the board of Vote Leave would mean "major obstacles" to a merger between the groups were removed.

Leave.EU campaign founder Arron Banks said the majority of people want a united "Brexit" campaign. He urged the newly appointed Lord Lawson " to pick up the phone as soon as possible, so we can finally come together and fight this referendum as a single united front."

Finance Secretary John Swinney has repeated that the Scottish government is working towards a 12 February deadline for a deal on the fiscal framework. 

But he said Scottish ministers would "give all the time possible to secure a deal". Earlier, it emerged that the deadline to try and strike a deal between the UK and Scottish governments could be breached.

The UK government has announced that detailed scrutiny of the Scotland Bill in the Lords is being delayed to allow more time for talks on the framework to continue.

Separately, the chairman of Holyrood's Devolution committee said a deadline of 3 March for his committee to report to Holyrood on any deal stood. Bruce Crawford said the committee would have to hear evidence "well in advance" of that date.

Former Tory chancellor Lord Lawson has been named as the chairman of a group campaigning for the UK to leave the EU.

The 83-year-old will chair Vote Leave, one of two groups vying to be the official Out campaign in the EU referendum.

The group's CEO Matthew Elliott, campaign director Dominic Cummings and company secretary Victoria Woodcock are leaving the board.

These changes were previously planned, Vote Leave said.

This just in from the BBC's David Porter:

It has emerged that the deadline to try and strike a deal between the UK and Scottish governments on the financial aspects of more powers for Holyrood could well be breached. This evening the UK government has announced that detailed scrutiny of the Scotland Bill , externalin the House of Lords is being delayed to allow more time for talks on the so called ''fiscal framework'' to continue. 

The Scottish government had said it wants agreement on this concluded by 12 February to allow any deal to be examined by Westminster and Holyrood. 

But it has emerged peers will not look again at the Scotland Bill until 22 February, a move being seen as the UK government making contingency plans for the deadline being breached.

A senior UK government source told the BBC that "it is important to get the deal right, not rushed''. 

In a letter to the convenor of the Holyrood devolution committee, Bruce Crawford, Scottish Secretary David Mundell says.

The former Conservative attorney general Dominic Grieve tells BBC Radio 5Live that he will be voting to stay in the EU because no-one has made a "coherent" case to the contrary based on a cost-benefit analysis of the UK's membership.

The prime minister has said he's "happy to be judged" on the proposals agreed with Donald Tusk, the European Council President, but said "we've got to work very hard in the next two weeks". In an interview with the BBC's political editor Laura Kuenssberg, Mr Cameron said:

Ed Vaizey, Minister of State at the Department for Culture, Media and Sport, says he believes the changes the prime minister has secured are "pretty unprecedented."

But Frank Field, Labour MP and former minister for welfare reform, argues the agreement is a "fudge" and that the PM has "given up" on his migrant child benefit pledge.

Questions over the UK and EU laws were explored by BBC deputy political editor James Landale when he spoke to Radio 4 World at One presenter Martha Kearney. 

They looked at lessons from Germany, and comments from the London mayor and MP Boris Johnson who said the prime minister was "making the best of a bad job".

Banks cannot assume regulation will be stripped back if Britain quits the European Union, Bank of England Deputy Governor Andrew Bailey says.

Critics of the EU claim leaving the bloc will mean Britain determining its own financial rules - and not being burdened with the bloc's regulation.

But Mr Bailey told the Commons' influential Treasury select committee that it would be "disastrous" to return to the light-touch bank capital regulation in place before the 2007-09 financial crisis, which left the public having to bail out lenders.

He also threw cold water on claims that leaving the EU would mean a "bonfire of red tape", saying Britain would have to have rules that were as strict as the countries it traded with.

"You wouldn't immediately assume there is a sort of golden world out there where it's all different," Bailey said, noting the United States' extensive regulatory framework.

Tracey McDermott, acting chief executive of the Financial Conduct Authority, told the committee, that being outside the EU would allow her to make slight changes, but that bank conduct regulation would remain much the same.

David Cameron has told MPs he will introduce measures to put the sovereignty of parliament "beyond doubt" - at the same time as he concludes the negotiations over Britain's reformed relationship with the EU.

The prime minister was responding to a challenge in the House of Commons by the mayor of London, Boris Johnson, who has been pushing for parliament to do more to assert its authority over Brussels.

Mr Johnson said: "Perhaps I can ask you how the change as a result of this negotiation will restrict the volume of legislation coming from Brussels, will change the treaties so as to assert the sovereignty of this House of Commons and of these houses of Parliament?"

Mr Cameron replied: "In terms of asserting the sovereignty of this House, that is something we did in 2010 through the European Referendum Act. It's something I am keen to do even more on - to put beyond doubt that this House of Commons is sovereign, and that is something we will look to do at the same time as concluding these negotiations."

This is the first time that Mr Cameron has directly linked the two issues and revealed that he is about to introduce plans for some kind of unilateral declaration of sovereignty.

It also suggests that this is how he will try to persuade Mr Johnson to vote to remain in the EU since this is an issue on which the mayor has campaigned for many months.

Downing Street is refusing to give details of the proposals which are being worked on by the Cabinet Office and the Ministry of Justice.

Eurosceptic Tory MPs are pushing for a repeal or amendment of the European Communities Act 1972 to assert that UK law has primacy over EU law. But critics say this would be tantamount to leaving the EU.

Instead, the government is looking at ways of asserting parliamentary sovereignty that would question and challenge EU decisions but without causing constitutional chaos.

Mr Cameron gave a hint last year in his 10 November Chatham House speech when he said ministers were looking at the way Germany used its constitutional court to test EU law.

He said then: "The Constitutional Court in Germany retains the right to review whether essential constitutional freedoms are respected when powers are transferred to Europe. And it also reserves the right to review legal acts by European institutions and courts to check that they remain within the scope of the EU's powers, or whether they have overstepped the mark. We will consider how this could be done in the UK."

SNP's Angus Robertson says broadcasters will concentrate on the EU referendum if it is held in June - at the cost of covering May's elections in Scotland, Wales, Northern Ireland and London.

He spoke out after first ministers Nicola Sturgeon, Carwyn Jones and Arlene Foster wrote to David Cameron urging him to defer the date.

"Of course the public can think two thoughts at the same time," Mr Robertson told the BBC, adding that his party is pro-European.

But, he stressed that if all the electoral events are held within weeks of each other, the focus of all the TV coverage will be on the EU.
