Capital gains on foreign employee shares

I have RSU’s received from my employer when I worked at Singapore. Paid relevant tax when they are vested in Singapore. Now I moved to UK and working for another employer. If  I sell the vested shares received by my previous employer, will I have to pay tax for capital gains?

Hi,

Yes, as they have already vested.

Thank you.

Thanks for the reply. Under any circumstances will there any relief for capital gains for those share awarded by employer?
