"There's been lots of up-sides for the UK since the treaty was negotiated in 2003, not much up-side for the French. The reason we wanted the treaty is that if you are found in a concealed vehicle, you're a clandestine, once you've set foot on British soil you can claim asylum whereas if you are found concealed in a vehicle on French soil you can't claim asylum for Britain so before that treaty was put in place, asylum claims were running at 80,000 a year in the UK. They are now running at about 30,000 a year. So we would probably see another 50,000 asylum claims a year.
