Unfortunately, the mayor of Calais, who has been in the post for 17 years and seen it all, is not so optimistic. Apparently, after the visit last Thursday, and a meeting with Yvette Cooper and Retailleau, the thoughts were:
"We were waiting for agreement today, clearly nothing has come. I don't think we were listened to nor taken seriously." (Taken from French news outlets).
Talking is good, but without confimation of anything happening soon, it seems that the UK millions are being spent by the French on fancy drones, thermal imagining equipment and troops who have no real powers. Fingers crossed there will eventually be a breakthrough.
