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.
