I just got travel cover for a trip to Bruges for £8.93 from MORE TH>N. This is the most basic policy, but covers my needs for this short trip. They pay £10 quidco cashback though (after a couple of months), so it's -£1!
It's for europe, excluding baggage, winter sports, Spain, and Cyprus.
Note - if you want it for -£1 - go through quidco. Do not use the Direct link
