Insurance Policy Maturity Benefits

Dear HMRC, I bought a target saving insurance policy in HK years ago. It is now matured and I am entitled to a receive a monthly amount, (USD1000 each month) as maturity benefit. Since the benefit paid out is a lumpsum amount (principal+interest). Pls kindly advise how I should report my tax return. Thanks
