Can foreign interest from long term fixed time deposit be apportioned?

Foreign interest from a fixed time deposit was paid in the tax year 2023/24. But the time deposit was for a duration of one year starting at the time before I arrived in the UK. On arising basis, can I apportion the interest paid only for the time I was in the UK and declare the apportioned interest in the Self Assessment? Or do I need to declare the full interest for the entire one year (including the time before I arrived in the UK)?

Hi May 2024
You need to declare it all as it was paid once you arrived here.
Thank you
