Hi,
We cannot comment on future events as legislation may change. However, based on current guidance, as you are resident in the UK, the gain would be reported here. If you are claiming the remittance basis, you would only report any gain if the income is remitted to the UK. You can see guidance here:
Remittance basis 2024 (HS264)
If you are declaring it in the UK, you can claim Foreign Tax Credit Relief for Indian tax paid on the same income.
Thank you
