As we don't seem to have arrived at any definite answer for the rest of Europe I doubt anyone has even thought about Switzerland. If they don't vote to end free movement presumably the same restrictions will apply for us travelling there as the rest of the EU. An interesting question is whether they are part of the Schengen area if they are it's pretty straightforward if not how do they know if a UK national has been there or in Schengen after next year?Europe will be closed a bit more if the Swiss vote to cancel free movement for EU nationals passes.
I am not sure what arrangements the UK and Swiss governments have made for 1st Jan onwards.
Anyone know?
