The Prime Minister and other European leaders are due to meet Turkish premier Ahmet Davutoglu tomorrow at a summit called to discuss the migration crisis around the Mediterranean. But on the eve of the Brussels meeting, Ukip leader Nigel Farage and Tory MP David Davis issued a warning about Turkish ambitions for EU membership. The pair, who are both campaigning for the UK to quit the EU, said Britain's security would be at risk if it remained in the bloc once Turkey had joined.

Mr Farage says it would be "downright dangerous" to admit Turkey into the EU, given the current flow of Islamic State terrorists in the region.

He said: "With net migration already running at record high levels, it is clear that remaining in the EU would mean migration into Britain running at even higher levels than they are today as well as a direct threat to Britain's national security. "Turkey wants to join the EU and has the support of Angela Merkel and David Cameron. This illustrates the risk in remaining in the EU: open borders with another 77 million people on top of the open borders that we already have to the entire EU.

"Plainly this is not just stupid, but downright dangerous given the current flow of Islamic State terrorists in the region. "Staying in the EU with eventual open borders with Turkey would represent a huge risk to Britain's national security."The Prime Minister must be asked why he believes Turkey should join the EU and why the UK should remain in the EU when open borders and EU expansion threaten the cohesion of our society and our national security?" Former shadow home secretary Mr Davis highlighted the a warning from the British head of Europol Rob Wainwright that as many as 5,000 ISIS-trained jihadists were roaming Europe.

He pointed out that Turkey has a long and porous border with Syria and Iraq, two of the most unstable countries in the Middle East, which meant that there would be easy access to Turkey for Islamist terrorists. Mr Davis said: "Giving visa-free access to people carrying Turkish papers will, if anything, make worse the security threat identified by Europol. "This demonstrates only too clearly why our membership of the EU, far from improving our security, actually puts it at greater risk." Turkish citizens could get access to the EU under Brussels free movement rules if the country joins the EU.

It would mean more than 70million Turkish citizens, who are overwhelmingly Muslim, getting the right to live and work in the UK. German finance minister Wolfgang Schauble said the summit would be a chance to work with Turkey to tackle the migration problem but played down the prospect of the country being admitted to the EU in the near future. He said Germany had "major doubts" about Turkey becoming a full member of the EU.
