Nigel Farage: Brexit only way to control immigrationpublished at 16:15
16:15Responding to today's net migration figures - which showed it is at its highest level ever - Nigel Farage has said the only way Britain can control of its borders is by leaving the EU.
The UKIP leader said the government's pledge to get net migration down to the "tens of thousands" was in "tatters", and added:
Quote MessageJust how can this or any government plan effectively for the future with our population rising so quickly and with open borders meaning we have no control over who can and can't come to Britain each year? A complete open door to the whole of the EU is madness."
Net migration 'appears to be out of control'published at 16:10
16:10Here's Home Affairs Committee chairman Keith Vaz's response to net migration to the UK reaching 336,000 in the year to June:
Quote MessageA third of a million people shows that reaching the government’s target is impossible if this trend continues. Net migration appears to be out of control. The home secretary needs to urgently explain why this has happened.”
Farron questions effectiveness of air strikespublished at 16:02
16:02BBC News Channel
Liberal Democrat leader Tim Farron says the prime minister made "a strong case" for air strikes but he says his party still has "a number of questions" about the UK extending its military action to Syria.
He says the proposal looks to be legal but the question is whether it is effective and in the UK's interests.
Eradicating IS is an act of self-defence and of solidarity with UK allies, he says. But he casts doubt on the figure of 70,000 Syrian opposition fighters to tackle the extremist group on the ground - something that has been challenged by other MPs, of all political persuasions.
Quote MessageWhat's very important is that we need to have operation on the ground otherwise air strikes will not be sufficient."

Labour seeks more detail on PM claim of 70,000 Syrian opposition fighterspublished at 15:55
15:55Ross Hawkins
Political correspondentA Labour source has said they still need to know more about the claim there are 70,000 Syrian opposition fighters who are not part of extremist groups.
Speaking after an inconclusive 90-minute shadow cabinet meeting the source said the figure was something they needed more information about.
The source suggested they might need to see the text of a motion before reaching a decision.
It was not unreasonable - the source said - to know what they were making a decision on.
The shadow cabinet resolved without a decision being made, the source said it was adjourned until Monday.
Labour's team will "try to move towards a collective decision".
The discussion was described as detailed, professional and businesslike.
MPs are now expected to discuss the issue with their local parties over the weekend.
Boris Johnson speaks out against Heathrow expansionpublished at 15:54

Quote MessageTo build this great engine of pollution in West London will cost far more than is estimated."
If a third runway was built, "the pressure would become overwhelming" for a fourth runway, he continues, adding that expansion would blight the lives of Londoners.

He advocates "competition between airports", arguing that new routes opening at Gatwick shows that competition works.
Mr Goldsmith also takes a dig at his Labour rival, Sadiq Khan, saying:
Quote MessageHis position on Heathrow is about as authentic as Donald Trump's hair."

End of twitter post'Tory spin' on Spending Review 'is unravelling' - Labourpublished at 15:25
15:25Labour's shadow chancellor John McDonnell has responded to the IFS's analysis for the Spending Review.
The economic think-tank has said the benefit changes announced by George Osborne will leave 2.6 million families on average £1,600 worse off by 2020.
Mr McDonnell said the "Tory spin" was "unravelling", and the party had been right to call it a "smoke and mirror" Spending Review. The IFS analysis showed Mr Osborne has "just delayed" tax credit cuts, rather than reversed them, he added.
