Fixed Deposit Interest across split year date

Hi HMRC, Before I moved to the UK, I started a 1 year Fixed Rate Deposit in a Hong Kong bank account. It only pays me interest on maturity. Before it matures, I moved to the UK and later became a UK resident. The fixed rate deposit matured and I received the interest. In my self assessment, I applied for Split Year Treatment. How much of this foreign interest should I report? Would it be the full amount I received on the maturity day or I can split the amount based on the overseas part and the UK part? Thank you.

Hi
It is the full amount on maturity as this is paid when you are in the UK.
