Capital gains on foreign stock received as gift

A friend in the US purchased stock for $10 a long time ago, and it is now worth $200. They plan to gift me several of these stocks. If I sell them in the UK, will I be liable for capital gains tax on the difference between when I received them and when I sell them, or would I also be taxed on the $190 increase from my friend's original purchase price?

Hi Stephan,
If you sell it will be the difference on what the value is when you received them against what you sell them for.
Thank you.
