British Prime Minister Theresa May's gamble on a June 8 snap election has been thrust further into doubt after a Survation poll showed her Conservative Party's lead had dropped to a new low of just one percentage point.
While British pollsters all predict May will win the most seats in Thursday's election, they have given an array of different numbers for how big her win will be, ranging from a landslide to a much more slender win without a majority.
In a sign of how much her campaign has soured just five days before voting begins, Survation said the Conservatives were on 40 per cent and Labour on 39 per cent, indicating May's lead has collapsed by 11 percentage points over two weeks.
"Prime Minister May's overall majority now hangs in the balance based on our most recent data," Survation founder Damian Lyons Lowe told Reuters.
May's personal rating turned negative for the first time in one of Comres's polls since she won the top job in the turmoil following the June 23 Brexit referendum.
The pollsters, though, indicated vastly different outcomes for May: ranging from a landslide majority of over 100 seats to a YouGov model which estimated that May would win 308 seats, too few for a majority in the 650-seat parliament.
Her party's lead over the opposition Labour Party was in a range of 1-12 percentage points, according to six polls published on Saturday. Four showed her lead narrowing, one showed her lead unchanged and one, ORB, showed it widening to nine points.
YouGov said May's lead was down to four percentage points, ICM said her lead had narrowed to 11 points from 14, Opinium said her lead had fallen to six percentage points from 19 points at the start of the campaign.
Comres found the Conservative Party's lead stood at 12 percentage points, unchanged from a week ago but far below the 21-point lead it recorded just before she called the election on April 18.
The Opinium poll for the Observer newspaper suggested May was set for a substantial parliamentary majority on June 8.
When May stunned political opponents and financial markets by calling the snap election, her poll ratings indicated she could be on course to win a landslide majority on a par with the 1983 majority of 144 won by Margaret Thatcher.
But since then, May's lead has been eaten away, meaning she might no longer score the thumping victory she had hoped for ahead of this month's launch of formal Brexit negotiations.
If she fails to beat handsomely the 12-seat majority her predecessor David Cameron won in 2015, her electoral gamble will have failed and her authority will be undermined both inside the Conservative Party and at talks with 27 other EU leaders.
