(Reuters) - Sterling weakened against the dollar late Wednesday after a new poll found that British Prime Minister Theresa May's Conservative Party's lead over rival Labour was just 3 points with just over a week to go before a national election.
Sterling edged about 0.12 percent lower against the greenback after details of the YouGov poll were published by the Times late Wednesday. It last traded at $1.2873 vs $1.2892 before the news crossed.
The British currency has been whipsawed by a series of polls that suggest May's once-commanding lead over Labour has shrunk dramatically as the June 8 election draws near.
Wednesday's poll indicated Conservatives held an advantage of 42 percent versus 39 percent for Labour. On Tuesday, a separate YouGov poll suggested that the election could result in a hung parliament.
