Speaking recently Mr Farage said: “Mr Cameron or 'Dishonest Dave' as I'm beginning to think of him.
"I don't believe a single thing this man says anymore.
"This man has campaigned for Turkey to join the EU consistently for 10 years.
"For 10 years, he's fought for Turkey membership and last night on the television he says 'Ah yeah, but we do have a veto'."
Mr Cameron told the Andrew Marr Show on Sunday: "There is no prospect of Turkey joining the EU within decades.
"It's simply not an issue, it's a total red herring and the out campaign know that.
"Some of them have admitted to it so they should stop frightening people because it's not going to happen."
FORMER defence secretary and senior Brexit campaigner Liam Fox has slammed the government over reports there are plans to allow visa-free travel for some Turkish citizens to the UK.
Documents leaked to the Sunday Times show there have been discussions of implementing visa-free travel to the UK for Turkish special passport holders – who number over one million. The leaked telegrams relate to the EU’s controversial deal to compensate Turkey for helping control the Syrian migrant crisis. Janet Douglas, an official at the British Embassy in Ankara, wrote: "We will need to develop our own lines on the UK’s stance to visa-free travel for Turks". She added: "One option would be to assess again the possibility of visa travel for Turkish special passport holders which would be a risk, but a significant and symbolic gesture to Turkey."
G Dr Liam Fox has hit out over claims the government is negotiating for Turkish visa-free travel
Dr Fox has suggested the government has not been transparent with the public over the Turkish issue.
He told the Today Programme: "It is very much against the assurances the government has given us.
"As a Conservative MP I am very worried about this.
"I think it is remarkable.
"On one hand we are being told these freedoms will not be granted.
"And yet secretly behind our backs there are discussions ongoing apparently about allowing [them].
Dr Fox’s fellow Leave campaigner Michael Gove has also slammed the plans.
"Later this year, if EU plans are implemented, then we’ll have visa-free travel for 77 million Turks throughout Europe," he said.
"It appears from this diplomatic telegraph today that there are suggestions that some special Turkish passport holders will be allowed to come to the UK as well."
He told the BBC: "The evidence is that the British government and the EU are actively working towards Turkey joining the EU and Turkish citizens being able to travel throughout the EU."
Home Secretary Theresa May and Foreign Secretary Philip Hammond, both campaigning for Remain, have described the story as "completely untrue".
