Cross border RSU taxation

Hello, I was granted RSU's that also vested in my home country that has a tax treaty with the UK. I was taxed on vesting in the home country. However, I sold those RSUs at a loss (compared to the vesting price) in the UK, and remitted the amount to a UK bank account. The questions I have are: 1. Can I claim the loss on sale in the UK or in my home country? 2. Will I have to pay CGT on those stocks sold in the UK at a loss? Is there any relief that I can claim at all? Thank you. Kind regards, RK
