Prime Minister David is to announced plans to stop British properties from being bought using "plundered or laundered cash" as part of a "global effort" to tackle corruption.

In a speech in Singapore, Mr Cameron will say that "anonymous shell companies" used to buy UK properties, often in London, will be exposed.

The speech comes during a four-day tour of South East Asia in an attempt to agree £750 million worth of trade deals.

Last year, a report by anti-poverty group One said $1 trillion (£600bn) a year was taken out of poor countries due to corruption. And last week, the National Crime Agency (NCA) said UK house prices were being pushed up by laundered money.
