Foreigners are allowed to work in Turkey; as long as they fit the necessary profile and are properly accredited. The same is true for Turks in the UK. Don't let's build a scandal out of simple misunderstanding of the rules.
Colwyn, I never usually take issue with your normally competent comments, my friend, but on this occasion I feel I must. Where else in this abortion of an idea that is the EU, can ANYONE who is able to reach our shores, pick up a bundle of " magazines " called The BIG Issue, stand on a street corner to sell said " magazine ", thus giving that person the status of being " Legally Self Employed "?? Through personal experience & knowledge of the BIG Issue , this is the loophole that is used by Turks who , somehow, find their way to our country, exploit this loophole, & then are able to form a system of gang culture in many of our cities, forcing British sellers of the self-same " magazine " to give up that franchise, under fear of physical beating , or worse !! Yet, as I said, it is a nightmare for any foreigner, Germans excepted, to be allowed to be in legal, gainful employment in Turkey !! I use this particular " magazine ", purely as an example of the disparity between the ease of Turks being allowed to work in this country, & the total, absolute lack of reciprocity shown by Turkey to all foreigners , except German Nationals !!
