Britain's Jamie Murray is to end his doubles partnership with John Peers at the end of the season to link up with Brazil's Bruno Soares.
Murray, 29, and Australian Peers, 27, have won titles in Brisbane and Hamburg this year and were also runners-up at Wimbledon and the US Open.
Their three-year partnership will end after the World Tour Finals in London in November.
Soares, 33, is a former doubles world number three.
The Brazilian has won 11 ATP tour titles with his current partner, Alexander Peya, 35, of Austria.
