Another point that has not been mentioned so much, is the 'pre-exsisitng condition'. It would seem that for many who have to take on this scheme would in effect be having to pay twice for possible hospital visits, tests, medication etc. For those it is also unfair, compulsory insurance, plus other costs they may already be paying for that will not be covered.
For those who are able to, I can see some people returning to the uk and returning here on 3 month tourist visas. I would imagine over this coming year, many ex pats will look closely at costs, savings etc and again where possible, spend less time in Turkey.
