Question Time continues on BBC One and on the Live Coverage tab above. Don't stop there - This Week follows straight on afterwards, rounding off a busy political day:

Restoring the Houses of Parliament without moving MPs and peers out would cost £5.7bn and take 32 years , a report has revealed

UKIP deputy chairman Suzanne Evans is facing the sack after she said party leader Nigel Farage was perceived as "very divisive"

David Cameron says his negotiations to reform the UK's relationship with the EU are getting "a good response"

Results of the elections to chair Parliament's powerful select committees were announced

It was announced that subsidies for new onshore wind farms would be ended a year early 

A man in the audience says the EU referendum question is "rigged" and says the options should be "in or out" not "yes or no". David Dimbleby turns to the panel's "expert on referendums" Alex Salmond - who believes the real problem is the lack of a "purdah" period before the poll.

Caroline Flint says she wants to see EU reform but will be voting to stay in because it is a "powerful trading bloc".

The value of the UK's exports to Belgium is the equivalent of our exports to India, Brazil and Russia combined, she says.

A man in the audience suggests leaving the EU, in order to renegotiate our way back in.

David Davis says the "scare stories" about job losses if the UK left the EU are "unmitigated rubbish". Switzerland and Norway, which are outside the union, are "pretty happy", he adds. Asked how he will vote in the in/out referendum promised by 2017, he says it depends on David Cameron's renegotiations - but concedes that "the one thing I want is probably more than we are going to get". He won't be leading the No campaign but might take part in it, he adds.

Alex Salmond says it would be "denying the reality of history" if the UK was not part of the EU. England and Scotland are European nations, he says.

Would it really be that bad if the UK left the EU, is the next question. Lionel Barber, of the Financial Times, thinks it would. Melanie Phillips says the UK has to be a self governing nation.

Columnist Melanie Phillips criticises the "political class" for "constantly saying this has got nothing to do with religion". Alex Salmond responds:

Young people need role models and to know "there is an alternative" says a man in the audience. Another audience member questions the level of responsibility of the women's families.

Alex Salmond says it is "impractical" to say the security services and police can prevent anyone from travelling to Syria. For all the stories about people who have "got through the net", there are plenty who have turned away from terrorism, he adds.

The first question asks whether it is right to blame the security services after three sisters from Bradford were feared to have travelled to Syria with their nine children. David Davis says it is right to ask the question but we need to find out more about what happened.

Question Time is up and running in High Wycombe. On the panel are Labour leadership contender Caroline Flint, Conservative MP David Davis, the SNP's Alex Salmond, columnist Melanie Phillips and Financial Times editor Lionel Barber.

Watch on the live coverage tab above.

Andrew Neil is joined by Diane Abbott and Michael Portillo, along with former Dewsbury MP Shahid Malik who will present a film on radicalisation.

The ex-Labour justice minister will say why he thinks the UK is failing as a nation to deal with the problem, and that mosques should provide a sense of a real Islamic morality.

The film rounding up the political week will come from Nick Watt - that's him dressed as The Stig - before comedian Josh Widdicombe joins the panel for the spotlight section.

That's all live at 11.35pm, straight after Question Time.

Announcing the formation of their "exploratory" EU referendum committee, the cross-party group of MPs say:

Seven MPs from three different parties have formed a group to act as a precursor to the Out campaign in the EU referendum.

The former Conservative cabinet minister Owen Paterson and UKIP's only MP Douglas Carswell are among them.

The "exploratory committee for the EU referendum" also includes Tories Steve Baker and Bernard Jenkin, as well as Labour MPs Kate Hoey, Kelvin Hopkins and Graham Stringer.

In a statement the committee says "this is not the Out campaign" but it adds "we are seeking urgently to provide resources for crucial thinking and to promote co-operation amongst those who might contribute to an OUT campaign".

Sources say that donors and professional campaigners are being approached.

UKIP's most senior woman is facing the sack after she told the BBC's Daily Politics party leader Nigel Farage was perceived as "very divisive".

Deputy chairwoman Suzanne Evans has been dropped as a party spokesman and officials in the party have been told to have no further contact with her.

The instructions are contained in an internal party email seen by the BBC.

Ms Evans had been speaking about what role Mr Farage might play in the EU referendum campaign.

"I think Nigel is a very divisive character in terms of the way he is perceived. He is not divisive as a person but the way he is perceived in having strong views that divide people.

She went on to say that she thought "somebody else" would front the out campaign in the in/out referendum, promised by 2017, but that Mr Farage should play a "significant part".
