One million British travellers planning to fly to Canada, the Caribbean and Mexico this year face the risk of being turned away at the airport – at the insistence of the US Department of Homeland Security.

New rules require British Airways and other airlines flying to certain airports outside America to submit passengers' personal data to US authorities. The information is checked against a "No Fly" list containing tens of thousands of names. Even if the flight plan steers well clear of US territory, travellers whom the Americans regard as suspicious will be denied boarding.

Simon Hughes, the deputy leader of the Liberal Democrats, told The Independent: "The concern by the US for its own security is entirely understandable, but it seems to me it's a whole different issue that American wishes should determine the rights and choices of people travelling between two countries neither of which is the US."
