Sue Barker presents live coverage of the concluding day's singles matches between Great Britain and Japan in their Davis Cup first-round tie in Birmingham.

Andy Murray won all eight of his singles matches in the 2015 competition as Great Britain lifted the trophy for the first time in 79 years.

Murray is likely to have a pivotal role to play on the final day of this best-of-five-matches tie against Japan, who have their own top-10 player in Kei Nishikori.
