If Turkey refuses to extradite me to the UK, can I still face prosecution?

Yes, under Turkish law, if extradition is refused—particularly because you hold Turkish citizenship—Turkey may initiate domestic criminal proceedings against you for the alleged offence. The UK must formally request this and provide evidence to Turkish prosecutors. Turkish courts apply their own procedural rules and sentencing guidelines, which may differ significantly from UK outcomes. This process, known as vicarious prosecution, ensures you do not escape accountability simply because extradition is barred. Any sentence imposed would be served in Turkey under Turkish prison conditions.
