MP Mike Hancock has been suspended from the Lib Dems after the party saw a report into claims of sexual misconduct. He denies the claims.
ITV News has seen an email in which Mike Hancock's office responded to his accuser, saying the claims against the MP were "not fair."
The Liberal Democrats have suspended the membership of Portsmouth South MP Mike Hancock following a report on alleged sexual impropriety.
The Liberal Democrat Business Secretary Vince Cable has told ITV News that the issues over immigration are of "genuine concern to lots of people" and that he won't get into a "party political barney" with opponents or Coalition partners.
The Conservatives' new immigration minister James Brokenshire had earlier said that Mr Cable was "incorrect" over the seriousness of the figures and also stated that wealthy Britons are "benefiting from immigration".
Ed Miliband should not be sucked into a pact with the Liberal Democrats and instead show the courage to rule on a minority government, Unite General Secretary Len McCluskey said.
"Labour, I hope, win the next election outright, but if they are the biggest party then my view is Ed should have the courage of his convictions and govern on a minority government," , Mr McCluskey said in an interview with the BBC's Newsnight programme.
"My view is that Ed shouldn't be sucked into a Lib/Lab pact he should have the courage of his convictions if we are the largest party, he should govern.
"And he should challenge those coalition parties to bring him down if necessary and go back to the people so that there's a stark alternative."
Ed Miliband should rule out a coalition with the Liberal Democrats even if Labour fail to secure a majority in next year's general election, one of the party's biggest backers has said.
Unite General Secretary Len McCluskey urged Mr Miliband to say he would govern alone even if the party falls short of a majority in next year's general election.
The comments come amid reports that David Cameron will make a commitment not to sign another deal in the event of a hung parliament.
Speculation that a potential alliance between Labour and the Lib Dems has increased in recent months, after Nick Clegg praised the way the opposition had "changed" under Mr Miliband's leadership.
David Cameron will rule out forming a second coalition government even if he fails to secure a Commons majority in the general election next May, the Daily Telegraph report.
Mr Cameron reportedly wants to make a commitment in the Conservative Party manifesto not to sign another coalition agreement in the event of a hung parliament.
A source told the newspaper that the Prime Minister is very clear that he does not want another coalition and believes a commitment in the manifesto would send a clear message to voters.
The Conservatives were forced to form a coalition with the Liberal Democrats in 2010 after failing to win enough seats.
UKIP leader Nigel Farage has accepted a challenge from Deputy Prime Minister Nick Clegg to a public debate over Britain's membership of the European Union.
Mr Farage told the LBC radio station that he wants other party leaders involved in the debate also.
Accepted Nick Clegg's offer of a debate, hope the others join in too. Ed's been particularly quiet...
Making the call during his weekly radio show on Thursday, Mr Clegg said he was "very happy and very keen" directly to pit the Liberal Democrats' support of UK membership of the EU against Ukip's desire to withdraw.
Liberal Democrat peer Lord Rennard has given his party until Thursday to lift his suspension or face legal action at the High Court in a legal letter issued at the party's headquarters.
Former Lib Dem chief executive was suspended on January 20 after failing to apologise to a number of women who had made sexual harassment complaints against him despite Nick Clegg telling him: "No apology, no whip".
Rennard's letter is understood to name individuals involved in the suspension decision, including the chairman of the Lib Dem regional parties committee Mike Wheatley and the chairman of the English Council of Lib Dems Peter Ellis.
A party spokesman said: "We have received a legal letter last Thursday. It does not constitute serving legal papers."
London mayor Boris Johnson has repeated his call for the tax rate to be cut to 40p - and declined to rule out the possibility of it happening before the general election.
Earlier, the Liberal Democrat Chief Secretary to the Treasury - Danny Alexander - said the rate would be cut "over my dead body".
"The last thing I want to see is a pointless sacrifice from the Liberal Democrats, let alone the dead body of Danny Alexander," he told BBC Radio 4's Today programme.
"Sooner or later there will have to be a new Conservative manifesto and I can't believe we are going to go into an election on a campaign to keep our tax rates higher."
Asked if that meant he accepted it could not happen until after 2015, he said: "Who can say what will happen to Danny Alexander? Stranger things have happened at sea."I don't think that it is reasonable always to keep UK tax rates higher than those of competitor countries.
"UK income tax is now higher than the average in the EU. That never used to be the case. I don't see why it should be the case for the long term and I see no reason why we shouldn't bring it down."
Chief Secretary to the Treasury Danny Alexander said the Liberal Democrats would not allow a cut to the top rate of tax in this Parliament.
In an interview with the Daily Mirror, he was asked about David Cameron's refusal to rule out cutting the top rate and replied: "You'll have to ask them (the Tories) why they answer those questions in those ways.
"If you ask me would I cut the top rate below 45p the answer is 'no'. In this Parliament we will not allow that to happen."
Mr Alexander also had some praise for Labour's Ed Balls - amid questions over whether the Lib Dems could work with the party in a future coalition.
"I play cricket with Ed Balls. I have opened the bowling at Lords while he kept wicket behind the stumps and I have to say he didn't let anything past him. So I would endorse him as a wicket keeper," he said.
Danny Alexander, the Liberal Democrat Chief Secretary to the Treasury, said any cuts to the top rate of tax before the next general election will be "over my dead body".
Mr Alexander made the comment as he dismissed calls from some Tories who want to see the rate reduced from 45p to 40p before the 2015 poll.
David Cameron fuelled speculation by repeatedly refusing to rule out further trimming the rate for those earning over £150,000 a year. It fell from 50p last year.
But in an interview with the Daily Mirror, Mr Alexander said: "I think it is right at 45%. I wouldn't go to cutting below 45%.
"I would say that would happen over my dead body.
Education Secretary Michael Gove's deputy, the Liberal Democrat David Laws, is reportedly determined to ensure that "Conservative game-playing" does not destroy the schools inspectorate Ofsted.
A "Liberal Democrat source" is quoted in several publications saying that "the decision to get rid of [Ofsted chair] Sally Morgan had absolutely nothing to do with her abilities, or even education policy, and everything to do with Michael Gove's desire to get his own people on board."
The move by Mr Gove threatens to "destabilise" and "undermine the independence of" the schools inspectorate, the source is quoted as saying.
