Capital Gains Tax on Oveseas Property

As a British passport holder, I have lived as a UK non resident overseas in Europe for the last 10 years in a property I own. I plan to move back to the UK, buy a UK home and sell my overseas home. I will have to pay increased stamp duty, as the UK property will be a second home, but when I eventually sell my overseas property will I be able to claim the addition stamp duty back, and will I have to pay Capital Gains Tax on this property? Thanks,

Hi, 
For stamp duty please refer to Stamp Duty Land Tax.
We cannot comment on future events as legislation and/or plans may change but based on current guidance, if the property abroad is sold prior to yor move to UK no CGT would be due.
Thank you.
