Britain could double its number of attack submarines as part of a landmark defence pact with the US and Australia.

The agreement, first announced 18 months ago, is designed to help the Australians replace their ageing equipment - and is widely interpreted as a bid to curb China’s influence in the Indo-Pacific region.
