LONDON (REUTERS) - British Prime Minister Theresa May's gamble on a snap election was under question on Thursday (June 1) after a YouGov opinion poll showed her Conservative Party's lead had fallen to a fresh low of 3 percentage points just a week before voting begins.
A failure to win the June 8 election with a large majority would weaken May just as formal Brexit talks are due to begin while the loss of her majority in Parliament would pitch British politics into turmoil.
In the strongest signal yet that the election is much closer than previously thought, May's lead has collapsed from 24 points since she surprised both rivals and financial markets on April 18 by calling the election, YouGov data showed.
The opposition Labour party polled 39 per cent against the Conservatives' 42 per cent. A YouGov model based on different data estimated May's Conservatives would win 317 seats, nine short of an overall majority of 326 seats.
After a hectic campaign which was suspended by a suicide bombing last week, pollsters have offered a vast range for the result of the election: From May losing her majority to a landslide victory for her Conservatives of more than 100 seats.
Betting that she would win a strong majority, May called the snap election to strengthen her position at home as she embarked on complicated Brexit negotiations with 27 other members of the European Union.
But if she fails to beat the 12-seat majority her predecessor David Cameron won in 2015, her electoral gamble will have failed and her authority will be seriously undermined.
If May failed to win an overall majority, she would be forced to strike a deal with another party to continue governing either as a coalition or a minority government.
That would have uncertain consquences for Britain's US$2.5 trillion (S$3.4 trillion) economy, and future government policy on everything from government spending and corporate taxation to bond issuance.
Sterling weakened against the dollar late on Wednesday after the YouGov poll, but was trading at US$1.2857 on Thursday, about 3 cents above where it was trading at the start of the campaign. The FTSE posted its best month of the year, helped by a weaker pound.
BRIGHT BREXIT FUTURE?
YouGov said May was still the most favoured choice for prime minister, though her 43 per cent rating is the lowest it has ever been.
Labour leader Jeremy Corbyn is on his highest ever rating of 30 per cent.
Corbyn, a 68-year-old peace campaigner, has been pulling in big crowds at rallies across the country, despite warnings from opponents in his own party that he is leading Labour to the worst defeat in its history.
May, an opponent of exiting the EU who won the top job in the political chaos following the shock June 23 Brexit vote, used a speech on Thursday in northern England to pitch her vision of Brexit.
"Set free from the shackles of EU control, we will be a great, global trading nation once again bringing new jobs and new opportunities for ordinary working families here at home," May said. "You can only deliver Brexit if you believe in Brexit," she said from behind a lectern with the slogan "A Brexit deal for a Bright future".
May backed the "remain" campaign in the run-up to last year's referendum on EU membership, though she made few public appearances.
May has repeatedly sought to present herself as the only party leader able to make a success of Brexit, though she has given few details of how she will handle the negotiations.
The Financial Times came out publicly for May, saying she was the safer bet, though The Sun newspaper, Britain's top selling paper, cautioned that May's campaign was far too defensive.
"Corbyn is selling a wonderland," The Sun said. "And even if his promises are practically impossible and economically catastrophic, set against the Tories' unnecessarily defensive campaign, it's small wonder he appears to be picking up support."
May was taunted by other party leaders for not attending a televised debate with them. Instead, May sent her interior minister, Amber Rudd, who dismissed the leaders as members of a "coalition of chaos".
The Financial Times said in an editorial that an increased Conservative majority could lead to more hardline Eurosceptics in May's party.
"Her resolve on Brexit is not in doubt; but her ability to deliver the best deal for Britain in terms of the closest possible relationship with the EU is worryingly unclear," it said.
