Sue Barker presents coverage from Great Britain's Davis Cup tie against the Ukraine at the Braehead Arena in Scotland.

It is the second day of the three, which features the doubles rubber. Andy Murray is Britain's top player by a country mile but GB captain John Lloyd must decide whether to ask him to take on the doubles in addition to his two singles matches.

Given that Britain have won the doubles rubber - so often a crucial turning point in the contest - just twice in their last eight ties, with Murray winning just one of his five doubles appearances, it will be a tough call. At stake is a place in the World Group play-offs later in the year. Commentary from Andrew Castle and Greg Rusedski. Show less
