Capital Gain tax from previous Tax residency

Currently I am UK tax resident. Previously I was living in Singapore and was Tax resident there. During my time in Singapore, I invested in some shares. So if I sell them now, where should I be paying capital gain tax. I want to understand what are the thing I should be declaration in Self-assessment here in UK. I am Indian citizen.

Hi,
If you are in the UK when sold the tax will be paid here.
Thank you.
