– This is the script of CNBC's news report for China's CCTV on June 5, Monday.
Welcome to CNBC Business Daily, I'm Qian Chen.
British Prime Minister Theresa May's gamble on a June 8 snap election was thrust 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 victory to a much more slender win without a majority.
Some of the polls indicate the election could be on a knife edge that would throw Britain into political deadlock just days before formal Brexit talks with the European Union are due to begin on June 19.
Survation said the Conservatives were on 40 percent and Labour on 39 percent, indicating May's lead has collapsed by 11 percentage points over two weeks and that her majority was now in doubt.
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.
May called the snap election in a bid to strengthen her hand in negotiations on Britain's exit from the European Union, to win more time to deal with the impact of the divorce and to strengthen her grip on the Conservative Party.
However, her lead has been eroded recently, which indicates that she might no longer score the thumping victory over socialist Labour leader Jeremy Corbyn she had hoped for ahead of Brexit negotiations.
YouGov said May's lead was down to four percentage points. The latest YouGov prediction model shows the Tories winning 308 seats, Labour on 261 and other parties winning 80 seats in the 650-seat lower house of parliament.
That is to say, if May 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.
But regarding to the question of whether or not the terrorist attacks over the weekend will impact global finanaical markets, analyst Tai Hui, Chief Asia Market Strategist from J.P. Morgan Asset Management, believes that the impact might be limited.
[TAI HUI J.P. Morgan Asset Management Chief Asia Market Strategist] "If you look at varies of attacks in the past 6-9 months in Europe or other parts of the world, their impact or impression of the market tends to be very limited if at all. Obviously, if that does lead towards a change in political landscape in the UK for the election this week, or Europe more broadly over the course of the next several quarters, obviously that might have a marginal market impact but unfortunately despite this terrible attacks, the impression of the market tends to be very limited."
Meanwhile, Theresa May has put tech companies on alert once again, saying they cannot continue to allow extremists "safe spaces" online.
Google, Facebook and Twitter were among tech companies that have been already facing pressure to tackle extremist content, but the pressure intensified after the attacks over the weekend.
And these tech giants said they were working hard to fight extremism.
