United Kingdom is the fifth-largest exporter of arms, although its exports volume has declined by 13%, comparing with the previous period, from 2000 to 2004. The U.K.’s arms sales make up 4% of the global market, SIPRI says. 21% of the U.K.’s weapons exports went to the U.S., including MP aircraft radars. The U.S. is the largest of UK’s recipients, followed by India (14%) and Chile (9%), SIPRI reports. Pictured above, Britain's Prime Minister Gordon Brown (L) and his Indian counterpart Manmohan Singh.
