U.K. Prime Minister Visits Bataclan Theater in Paris

After holding talks, the two leaders said they had agreed to increase intelligence sharing and cooperation on counter-terrorism matters against ISIS. We have shown our firm resolve and together we will defeat this evil threat’.

In the Commons, Mr Cameron confirmed he would set out his comprehensive strategy on Thursday; members of the Foreign Affairs Committee are returning from a fact-finding mission to Iran a day early so they can attend the PM’s statement.

Hollande is due to meet with US President Barack Obama and Russian President Vladimir Putin this week as part of plans to step up efforts to combat ISIL in Iraq and Syria.

Writing in Monday’s “Daily Telegraph” newspaper, the prime minister said: “As the murders on the streets of Paris reminded us so starkly, Islamic State is not some remote problem thousands of miles away; it is a direct threat to our security”.

‘We will intensify our strikes, we will cause the greatest damage possible to this terrorist army.

“Our air forces have been told to strike and strike hard against Daesh”.

With 26 fighter jets on board, the 38,000t, nuclear-powered French aircraft carrier group, which includes frigates, a submarine, and a fleet auxiliary supply ship, was deployed last week to the eastern Mediterranean to support coalition operations in Iraq and Syria.

The UN Security Council’s recent resolution authorizing countries to “take all necessary measures” against IS may also sway undecided politicians.

“The prime minister would welcome support from across the House on this issue”, Cameron’s spokesman said Monday, adding: “When the prime minister feels he has the consensus, he will go back to the House”.

Defence Secretary Michael Fallon, who is to brief Labour MPs next Wednesday, would not be drawn on when MPs would be asked to vote but said the UK’s military capability – such as the use of Brimstone missiles – would be an important contribution to the global fight against extremists.

He said: “It is ridiculous we can get more information from countries outside the European Union than we can from each other”.

“It has already taken the lives of British hostages and carried out the worst attack against British people since 7/7 on the beaches of Tunisia, to say nothing of the seven terrorist plots right here in Britain that have been foiled by our security services over the past year”, he said.

Speaking on the Radio 4 Today programme, she said Cameron could win some support from Labour MPs if he made a compelling case.
