My right hon. Friend the Foreign Secretary has used strong language in his statement. He says that Islamic State is “an evil which is a direct threat to our national security.” He says that it is possessed of a “poisonous ideology”. He says that it is “a barbaric force that has no place in human civilisation in the 21st century”; and he says that it “represents a major threat to us, here at home, particularly at the hands of returning foreign fighters”. Given that, with the assent of this House, Her Majesty’s armed forces are now engaged in military action against Islamic State, given that we have all witnessed on television the beheading by a British jihadist of British and American aid workers, and given that the offence of treason still exists, but has not been used since 1946, will the Foreign Secretary ensure that British jihadists who return from Iraq and Syria are prosecuted for the offence of treason? Their actions are treachery against Her Majesty, and
aiding and abetting enemies of Her Majesty is one of the greatest offences a British citizen can commit. The message should go out from this House—
