'Let's Do This:' Andy Murray tweets support for Scottish independence on day of vote

Murray’s future status, as well as that of Scottish Olympic athletes, rests on the result of next week’s independence referendum in Scotland. Polls suggest the two sides are running neck-and-neck, presenting a real possibility that Scotland could break away after 307 years as part of the United Kingdom. If Scots vote ``yes’’ on Sept. 18, the decision won’t have much impact on football and rugby, as Scotland already fields its own teams in those sports. But it will affect Scotland’s status in the Olympics and raise doubts over whether Scots can send a team to Rio. By then, Murray could be representing an independent Scotland.

After years of carefully avoiding taking a side on the issue, former Wimbledon champion Andy Murray has signaled his support for Scottish independence.

Murray, who is Scottish, sent out a post on Twitter early Thursday, just hours ahead of the polls opening on the referendum to break away from the United Kingdom.

Murray indicated that negative campaigning by the anti-independence side had made up his mind.

He tweeted to his 2.7 million followers: "Huge day for Scotland today! no campaign negativity last few days totally swayed my view on it. excited to see the outcome. lets do this!"

In 2013, Murray became the first British player in 77 years to win the Wimbledon's men's title. He also won a gold medal for Britain at the 2012 London Olympics.
