Taxation of a worker in Switzerland resident in the UK

Good morning, I apologise for bothering you, but I couldn't find the information when reading the legislation, which seems to me to be based in this case on the criterion of citizenship. I am an Italian citizen working in Switzerland at a university, with a cross-border commuter permit. I am not in fact a Swiss citizen. I will have to go and work in the UK for two consecutive years, with a fellowship in a British university, paid for by Switzerland. I will then become resident in the UK. What will the taxation be for an Italian citizen who works on salary from Switzerland in the UK and is resident in the UK? Thank you very much.

Hi Gvn,
Please refer to: Tax on foreign income.
Thank you.
