CGT on Unremitted Gains from RSUs Granted in UK

Hello, I'm a non-domiciled UK resident, filing on the remittance basis -- I received RSUs from employment in the UK, and paid taxes through PAYE at the time of vesting (on the vested amount). The resulting vested shares were then deposited into a US account. I later sold those shares for a capital gain (still in the US account) and it hasn't been / won't be remitted to the UK. Would this capital gain then be considered a foreign gain, or a UK one? Thank you for the help, it's much appreciated!

Hi, thanks for the response! If it's alright, here's a more general version of the question (if it's still too narrow though I'm happy to go another route): Are capital gains on vested shares in a foreign company that are held in a foreign account, but originally earned for work in the UK, considered foreign income?

Hi,
Yes.
You have boughrt them from money earned in the UK but they are based abroad>
Thank you.
