Out of curiousity about Switzerland and Schengen:
1. When were the Swiss allowed to use Schengen/E.U. privileges through U.K. immigration? A few years ago (when Schengen had been implemented), I was in an immigration line at LON in front of a group of Swiss travellers.
2. As of April last year, there were cursory document checks going into and out of Switzerland from France (the French weren't really checking on people coming in from Switzerland).
