Britain became the world's largest arms exporter last year, according to government figures released yesterday, overtaking the US which normally occupies the top slot.

The UK won £10bn of new defence orders in 2007 from overseas, giving it a 33 per cent share of the world export market, according to figures released yesterday by the Defence and Security Organisation, set up to promote Britain's defence exports. Export orders totalled £5.5bn in 2006.
