Remaining in Europe

I am a British Citizen, if my Uzbek Fiance marries me in Prague for example is she entitled to remain within the European Union and enter the United Kingdom with me? On the basis that she is now my spouse dependant?

The earlier post regarding foreign spouses of EU Nationals was helpful

Have you been working or studying in mainland Europe? Or can you prove that you were self-sufficient there...and paying for health provision?
You will need to be able to do that for your wife to enter under EU regulations.
You could however, (if you meet all the requirements of finance, accomodation and proof of genuine relationship) apply under UK law for her to enter as your spouse once the visa has been issued. More expensive option however and you would both have to be 21 or over.
