Re: a second *binding* referendum and cancel the madness that is Brexit.
Well _this_ Remainer wants to join Schengen and the Euro, and I believe dropping the rebate would be a small price to pay for that. However I recognize that these are not particularly popular choices in the UK. Achieving EU membership _without_ a commitment to Schengen and the Euro can only realistically be done by remaining a member. (There's also the point that Spain might be difficult about Gibralter if we tried to rejoin.)
