In an interview with the Guardian, external prospective Lib Dem leader Tim Farron has spoken about his Christian faith.

Asked if he consulted God when considering whether to stand for the party leadership. He replied: “Of course you do, of course you do. Obviously you ask for His guidance...” 

“I think He has a plan for everybody...” 

"Well, God is sovereign. Dreadful things happen in this world, but that reminds us that we need a saviour. 

"I don’t go round fixating that God has some major plan for me. Maybe his plan is for me to lose a bunch of elections and be humbled. God’s plan could be that some pretty brutal things happen to you. But the one thing I fall back on is that God’s overall plan is good.”

Yesterday, former Labour leader Ed Miliband caused much hilarity on Twitter when he revealed he had been mistaken for Nick Clegg by a member of the public.

Leading the review is committee chairman Lord Best, who said: "The public purposes of the BBC cut right to the heart of what the organisation is for. 

"They were introduced ten years ago during the last charter negotiations and the Committee feel that, in the light of industry, cultural and technological developments, it is the right time to review them.

“Much excellent work has already been done on the BBC’s future, but we want to delve further into two issues that we believe to be strongly connected: what exactly are the fundamental purposes of the BBC; and is there a better way of setting the licence fee whilst also ensuring the BBC’s independence?"

"Network Rail provided that detailed assessment after the election and, as a result, the scale of Network Rail's problems have only now become clear.

David Cameron, says it was "never going to be the case" that Britain's new relationship with Europe would be enshrined in treaties before the referendum.

The BBC revealed yesterday that Mr Cameron had accepted in talks with other EU leaders that there would only be a "legally binding" promise of treaty change before the referendum, which must take place by the end of 2017.

Speaking in Brussels, the prime minister said: "What is being discussed here is a substantial package of changes including treaty change that need to be agreed before there's a British referendum. It's the agreement of the package - including treaty change - that must happen.

"But it was never going to be the case that you would get all 27 other parliaments to pass treaty change before you have your referendum.

"But this isn't in anyway strange...

"What matters is getting the substantial agreement and then taking that to the British people in a referendum."

Asked if he should have started laying the groundwork for his reform negotiations five years earlier - a frequent criticism of the PM - Mr Cameron said he did a lot of diplomacy when he first became prime minister.

Mr Cameron said there had been "some very thorough and thoughtful arguments" put forward and the conversations worked on the basis of "mutual respect".

"I'm not saying that everyone has immediately put up their hand and said 'yes David you can have whatever you want'," he added.

Prime Minister David Cameron speaking now at a press conference in Brussels said he believed that his negotiations with several European leaders had "gone well" but he acknowledged that there was still "a lot of work to do".

"I think people can see that Britain has got a legitimate set of questions and a legitimate set of asks," he said.

The Prime Minister David Cameron says the UK will do "all we can to help" in the aftermath of the "appalling events" in France and Tunisia.

Speaking in Brussels, Mr Cameron said "our hearts go out to the victims" of the terrorist attacks in the two countries.

He said he had offered his "sympathy and solidarity" to the French President and would speak to Tunisia's leaders later today.

Mr Cameron said the terrorist threat "faces all of us" and "can happen to all of us" and the UK would co-operate on counter-terrorism, including "dealing with the threat at source".

He said it was also important to "deal with this poisonous radical narrative that is turning so many young minds", including in the UK.

Prime Minister David Cameron is planning to focus his EU referendum campaign on the "risky" consequences of British exit, according to a leaked document detailing the prime minister's negotiations. 

The note, obtained by The Guardian, external , is reported to be an account of a private meeting between Mr Cameron and one of his 27 EU counterparts during a round of meetings ahead of this week's European Council summit.

The note says Mr Cameron has set himself the "firm aim" of keeping the UK in the EU, according to the Guardian.

The note also says: "He [Mr Cameron] believes that people will ultimately vote for the status quo if the alternatives can be made to appear risky.”

The document also suggests that Mr Cameron would like to hold the referendum next year ahead of the December 2017 deadline.

The government's emergency Cobra committee will meet this afternoon following terror attacks in France and Tunisia, David Cameron said as he offered "our solidarity in fighting this evil of terrorism".

More tragic news is now being reported from Tunisia where a terror attack on two hotels in a tourist resort is thought to have killed several people.

A Department for Transport source firmly denies any suggestion they knew before the election that electrification would have to be paused but chose not to tell anyone.

The source said information only came to light "in the last week or so" revealing they would be forced to call a halt to work on the Transpennine and Midland Mainline routes.

The government and regulator have both made public statements making clear there were major problems.

In March the transport secretary Patrick McLoughlin himself told a select committee the date for the Transpennine electrification would slip.

But the source was insistent they only knew things were so bad a pause was necessary very recently.

That account is supported by a Network Rail source.

The transport minister responsible for part of the government’s so-called “Northern Powerhouse” policy has insisted the electrification of trans-Pennine and Midland Mainline rail services has been paused, rather than stopped.

In an article for the YorkshirePost, external , Andrew Jones wrote: "This is a pause, not a stop, and this change to the team will strengthen it to make sure we deliver. We remain hugely ambitious and that is why the budget remains intact,"

 He said on routes between Sheffield and London, better services would be delivered before electrification. 

“In the meantime, we will deliver faster trains and better services for passengers on that route,” wrote Mr Jones, the MP for Harrogate and Knaresborough.
