Taxation of shares granted after moving to the UK

Hello I recently moved from Israel to the UK with a Skilled Worker Visa, about 6 months ago. I am employed with a public company and I have been given RSUs. The plan was granted *before* I moved to the UK. Could you clarify which country is primarily responsible for taxing the RSUs when they vest and are sold: the country where I was residing and working when the RSU plan was initially granted, or the UK, where I am now a tax resident? Thank you for your assistance.

Hi,
It will be the country you are resident in at the time of selling.
Thank you
