I don't think that UK will double tax it citizens if the income is reported in the country of origin of the income. So if you invest the money in another commonwealth country - like India, Malaysia or Singapore, they do not levy taxes on you again should you repatriate the monies.

There is no capital gains tax in Singapore - just normal Income tax, which anyone doing business or earning an income within our borders will have to pay an income tax.
