US Roth Pension Distribution

Hi, Can I confirm that a US Roth pension distribution, which is not taxable in the US, to a US person resident in the UK is also not taxable in the UK?

Hi

Roth Individual Retirement Accounts payments to a UK resident that are not taxable in the United States are not taxable in  the United Kingdom.  Have a look at DT19852 - Double Taxation Relief Manual: Guidance by country: United States of America: Treaty summary Note 2 in relation to other pensions. 

Thank you
