Hello,
1. If you have also Turkish nationality, you should do recognition and enforcement your court decision about your divorce in Turkey. If you do not it, you cannot marry in Turkey. Maybe England authorities will ask it to you when you apply to them to remarry.
2. According to Turkish Law, you have to wait 300 days. But you can apply to the court to cancel this waiting period.
To do this, you should get information from a lawyer, directly.
Best regards,
