Earlier today, David Cameron held talks with Danish Prime Minister Lars Lokke Rasmussen in Downing Street.

Topics on the agenda included the planned UK referendum on European Union membership and the refugee crisis facing the continent.

Mr Rasmussen pledged to support Britain staying in the EU but warned the institution could not become a "social union".

Mr Cameron said Britain and Denmark were "very close friends", and had a close economic and trading relationship. He also said he was "heartened by what you [Mr Rasmussen] said in your election campaign about the need for European reform and support for the British renegotiation".

Nicola Sturgeon has said Scotland is ''willing and able'' to take a share of Syrian refugees immediately.

The first minister was speaking following a meeting with Foreign Secretary Philip Hammond.

She said Scotland could take a "proportionate number" of refugees, about 2,000, as part of the UK government's resettlement programme.

The UK government has pledged to take 20,000 refugees from camps Syria's borders over the next five years.

Northern Ireland's main political parties had a day of "focused and productive" talks in a bid to solve the ongoing crisis at Stormont, Northern Ireland Secretary Theresa Villiers has said.

Round-table discussions have begun over the issues of over paramilitary activity and welfare reform.

Ms Villiers said all parties had "committed themselves" to the talks.

The political crisis was sparked by the murder of ex-IRA man Kevin McGuigan Sr last month.

Times commentator Tim Montgomerie gives his response to Lord Ashcroft's unofficial biography of David Cameron, extracts of which have been published by the Daily Mail today.

He says it is "very embarrassing on a personal level" for the PM to be accused of the allegations, but he also wonders if it's slightly damaging for Lord Ashcroft as well, as he may be in danger of "looking a bit small for making these charges against the prime minister".

Meanwhile journalist Toby Young, a contemporary of Mr Cameron's at Oxford University, says Lord Ashcroft has been working on the book for "five years" and spent "millions" in the process, and the "headline-grabbing sensational story" is "completely implausible nonsense".

He says he's done numerous pieces of research on the PM's student days and no-one mentioned any such stories, adding:

There was a feisty debate at the Liberal Democrat conference this afternoon about Trident - Britain's nuclear weapons system. A few delegates talked about a vote in Parliament... so what is the state of play?

At the moment, the UK's nuclear weapons are based on four submarines. But these submarines are reaching the end of their lives. So in 2016, there'll be a decision on the size of the next fleet - which would enter service from 2028. (A decision on the weapons is expected in 2019.)

There are calls for Parliament to scrutinise - and vote on - the purchase of new submarines. But, according a House of Commons research paper, the government is under no obligation to give Parliament a vote. It's up to the government to decide how to involve Parliament in the decision. 

Nick Clegg is musing about the political system and the future of the Lib Dems at a fringe meeting organised by the think-tank Demos.

Reflecting on Britain's electoral system, he wonders how long a political system can survive when "it's clearly so out of whack with the natural ideological divisions that exist". He says the system has created an "accidental government".

As for the Lib Dems, he jokes: "The only way is up, that's for sure." 

He says the party will be ignored and derided until it starts winning elections again. "Things can change tremendously quickly. In 2010 we got more votes than we ever have done since the party was founded."

It has been a lively day in Westminster and down in Bournemouth so here's a round-up of what's happened so far.

- Former Lib Dem leader Nick Clegg has said his party can be the "comeback kids" of British politics

- Lib Dem members reject calls for the party to back the scrapping of Trident in a key early test of Tim Farron's leadership

- Lord Ashcroft says he is not seeking to "settle scores" with David Cameron after the serialisation of a book making new claims about what the prime minister knew about the peer's tax status and about the PM's time at Oxford University

- During a trip to China, George Osborne announces a string of business deals and confirms Chinese investment in the new Hinkley C nuclear power reactor. But a £2bn guarantee offered by the government is criticised. 

The Lib Dems have released a statement after the leadership won a high-profile vote on the future of Trident at the party's conference, seen as an early test of Tim Farron's leadership.

Journalist Isabel Oakeshott discusses the biography of David Cameron that she has co-authored with Lord Ashcroft, which contains claims about the prime minister's time at Oxford University in the 1980s. 

Good news for Tim Farron as the Liberal Democrats vote by 579 votes to 447 in favour of a holding a review of defence policy. It means that official party policy is not - as some Lib Dem members had wished - scrapping Trident altogether. Instead, Lib Dem members backed Tim Farron's compromise of a review - so that alternatives to Trident could be identified.

Lib Dems are now voting on whether to have an 18-month review of Trident policy. In a show of hands, it was too close to call so there's now a count going on. 

Nicola Sturgeon has said David Cameron has a duty to "address directly" the allegation that he knew of Lord Ashcroft's non-dom tax status in 2009, earlier than previously claimed. The Scottish first minister said:

Urging delegates not to back the motion, Baroness Shirley Williams tells conference that things are changing - citing Iran's decision not to pursue uranium refinement "because of endless diplomatic debate".

She says: "We are now on the doorsteps of a real attempt to try to remove the serious nuclear threats that exist in the world."
