Scottish independence: Andy Murray will play for Great Britain at the Davis Cup despite backing 'Yes' campaign

World No 12 broke his silence on the referendum yesterday

Andy Murray confirmed he will play for Great Britain in the Davis Cup match against the United States next March whatever the outcome of the Scottish independence referendum.

The world No 12 broke his silence on the subject with a tweet in the early hours of Thursday morning backing a 'yes' vote.

That left question marks over Murray's continued commitment to the British team should the union remain in place.

The 27-year-old has always stressed his pride at representing Britain in Davis Cup and at the Olympics, citing the singles gold he won in London two years ago as of equal importance to his two grand slam titles.

And Murray told the Daily Mail: "I will be playing for Great Britain in the Davis Cup next year, that is for sure. I will be there in March. As far as I'm concerned the vote doesn't change anything in that regard."

His doubles partner in two of the last three ties, fellow Scot Colin Fleming, has also backed independence, as has Murray's brother Jamie, with whom he has previously played in the competition.

Murray, who as a resident of Surrey does not have a vote, said of his intervention: "I've followed pretty much everything about it over the last two weeks, and especially in the last few days, and that's how I felt at the time

"It's not my decision, I can't vote, it's for the Scottish people to decide and I trust them to make the right decision.

"I will support whatever the outcome is. Regardless of how it goes, I think it's very important for everyone to come together and stick together afterwards."

Murray said during the recent US Open that he would expect to represent Scotland at the Rio Olympics in 2016 should there be a 'yes' vote.

The question of what would happen to the Davis Cup team in that instance has not really been addressed, but it could be that a unified British team remains in place.

Murray's tweet came on the same day as the draw for next year's Davis Cup World Group, where Britain were handed a first-round rematch with the USA.

Leon Smith's team secured their place at the elite level of the competition for a second consecutive season by upsetting the US in San Diego in February and then lost narrowly to Italy in the quarter-finals.

Because Britain played on US soil the last time the two teams met, this tie will be played in Britain from March 6-8.

USA had been favoured to win the last tie but their choice of clay backfired and James Ward's victory over Sam Querrey coupled with two wins for Murray decided it.

A home tie will not necessarily make Britain favourites this time, though, given USA were without number one John Isner earlier this year.

Picking a surface will not be that easy for Smith and his team, with the fast indoor court they have selected for home ties in the past also suiting the US.

And the prowess of the Americans' doubles team of Bob and Mike Bryan means whoever is picked as number two singles player - probably Ward - will likely need to win a rubber.

It will be Britain's first home match since April 2013, when they recovered from a 2-0 deficit to stun Russia at Coventry's Ricoh Arena.

Smith said: "This is obviously a big tie against very tough opposition who we know very well having played them earlier this year.

"That win was a fantastic upset, and we'll be looking to try and increase our odds once again and get another win, this time on home soil."

Victory for Britain over the US would mean another home tie against either top seeds France or Germany in July, while the pick of the other first-round ties are derby matches between Argentina and Brazil and Serbia and Croatia.
