You have made a capital gain of some 100K.
This is taxable in India at Income Tax rates. 0% on the first 200K rupees, 10% 200K - 500K, 20% 500 to 1 million and 30% thereafter. The conversion rate is currently of the order of 98.65. Your gain is thus 9.896 million IR. You will pay about 2.799 million IRs in tax; say GBP 28314.
Under the Double Taxation Treaty between the UK and India this tax is allowed against any UK Capital Gains Tax liability. As far as the UK is concerned you could be facing a tax bill of some 28K, worst case scenario, but the Ind***** *****ability is about the same so the tax credit will remove any UK liability.
So it all falls to what the Indian Tax authorities charge you. I do hope my reply has been of some assistance. You may well need a trusted local agent in India to assist in this matter.
