Following bloody Paris attacks that left 132 people dead, David Cameron has vowed to intensify the fight against the threat posed by Islamist militants.
He announced the Government plan of hiring additional 1,900 extra spies at the G20 summit in Turkey saying that Britain faced a "generational struggle" against IS, which he said intended to "destroy us and our values."
Speaking ahead of the announcement, the Prime Minister said: "I am determined to prioritise the resources we need to combat the terrorist threat because protecting the British people is my number one duty as Prime Minister.
During the G20 Summit, Barack Obama and Vladimir Putin has agreed that there's an urgent need for political transition in Syria. Although both countries want to eliminate IS, they remain at odds over tactics and the subsequent role of President Bashar al Assad.
Mr Cameron added: "We have our differences with the Russians, not least because they've done so much to degrade the non-ISIL opposition to Assad, people who could be part of the future of Syria."
"But the conversation I want to have with Vladimir Putin is to say, 'look, there is one thing we agree about which is we'd be safer in Russia, we'd be safer in Britain if we destroy ISIL, that's what we should be focusing on'."
