David Cameron encourages Scots to vote to stay in U.K.

LONDON, Sept. 9 (UPI) -- U.K. Prime Minister David Cameron will travel to Edinburgh on Wednesday to encourage Scots to stay in the United Kingdom as public sway leans toward independence.

The decision to address Scotland comes as anxiety in London grows over the Sept. 18 referendum that will determine whether Scotland will gain independence from the United Kingdom.

"There is a lot that divides us -- but there's one thing on which we agree passionately: the United Kingdom is better together," wrote Cameron, Labor Party leader Ed Miliband and Nick Clegg of the Liberal Democrats in a Facebook post announcing Cameron's plans Tuesday. "That's why all of us are agreed the right place for us to be tomorrow is in Scotland, not at Prime Minister's Questions (PMQs) in Westminster. We want to be listening and talking to voters about the huge choices they face."

Concern in Westminster heightened after a poll released by YouGov over the weekend showed the pro-independence movement in Scotland gaining a slight edge a week ahead of the referendum.
