Tom Tugendhat has called for the UK to update its treason laws in order to “bring ourselves up to date” and deal with British citizens who join terrorist organisations.
The Conservative MP told talkRADIO that Britain does not currently have “the right legislation to act on this”.
"I don’t believe that this is the last time that some stupid young people are going to go and join an idiotic death cult...and that's why I keep calling for a new Treason Act," he told Mike Graham.
Mr Tugendhat, chair of the foreign affairs committee, went on: “I wish we didn’t have to bring them back, I wish they could stay there, all of that would be great.
"But the idea that we’re going to set up some sort of tribunal in Iraq in the next year or two is just not real; it’s not going to happen - so how do we get these people off the battlefield so that they don’t just start up again in another country or another country?
“I think, bluntly, at the moment the best answer is to update our laws, bring them back here and lock them up.”
His comments come after The Sun reported that ministers have been warned that British jihadis, whose children have been brought back to the UK, could use human rights laws to re-enter the country.
Foreign Secretary Dominic Raab announced in November that the government was in the process of returning orphaned British children from the Syrian conflict.
In a statement he said: “These children should be safe and sound here in the UK at home, not caught up in that viscous conflict.”
