Labour continue to narrow the gap on the Conservatives with one YouGov poll putting them within five points of Theresa May's party.
The closing stages of the election have been rocked by the terror attack at Manchester Arena that killed 22 people on the evening of May 22.
Political campaigning restarted on Friday after being suspended in the wake of the attack. Prior to the attack Labour had been gaining on the Conservatives, albeit with a healthy deficit still left to overcome.
Some early polls had the Tories at almost double the vote share of the Labour Party led by Jeremy Corbyn, indicating that the most likely outcome would be a landslide victory that would increase her party’s current working majority of 17 in the House of Commons.
Theresa May's lead has dropped from 17.8 points to 10.5 since she called the election on April 18.
While the pollsters still give the Tories a clear lead, the apparent impact of early campaigning will be a concern to party headquarters, and a boost to their rivals.
Some experts had estimated that the Tories would take as many as 56 seats from Labour, leaving them with a 200-seat lead over the official opposition party, aided by Ukip's apparent collapse in popular support over recent weeks.
A healthy Tory majority is still on the cards, but Labour now look set to win more of the vote than they did under Ed Miliband in 2015. Theresa May won't be worried yet, but alarm bells will ring if her lead continues to narrow.

What are the betting odds for the UK general election?
For those who have lost faith in polling, there is another way of predicting electoral outcomes: ask people who are prepared to put their money where their mouth is. Many now believe that political betting markets can better predict elections, relying on the wisdom of a crowd of punters to sort and weigh all the probabilities.
Coral's latest odds for the election have Mrs May as most likely to continue as Prime Minister after the election. The latest odds for the party to emerge with the most seats are:
- Conservative - 1/16
- Labour - 8/1
- Lib Dems - 500/1
- Ukip - 1000/1
- Greens - 1000/1
What are the key battlegrounds?
The Conservatives are likely to gain a series of key target seats in the General Election, capitalising on their strong position in the polls.
An analysis of the 2015 general election results by The Telegraph has shown that around 58 seats in Labour's North and Midlands heartlands are under threat due to the Brexit effect in the upcoming snap election on June 8.
There are 58 Labour-held seats where the Conservatives are fewer than 9,000 votes behind and where the constituents voted Leave in the EU referendum last June – 37 of which are located in the Midlands or in the North of England.
The seat with the narrowest Labour majority is Halifax where the Conservatives finished just 428 votes behind Labour in the 2015 general election. This seat is particularly vulnerable due to the fact that Halifax voted to Leave the EU by 60 per cent.
The Tories will, however, face pressure from enthusiastic EU-backing Lib Dems who will seek to regain seats that they lost in the 2015 general election.
Mrs May currently holds Remain-backing Lewes with a majority of 1,083 (2.1 per cent) and Twickenham with a majority of 2,017 (3.3 per cent). Both of these were taken from the Lib Dems by David Cameron in 2015, and Tim Farron's pro-EU party will be seeking to win them back.
Who is voting for which party?
Class is no longer the dividing line in British politics with the Conservatives attracting considerable support from working-class voters according to recent polling.
Some 43 per cent of C2DE voters - which includes skilled and unskilled manual labourers, casual workers and pensioners - said they intend to vote Tory in the upcoming General Election, rising just three points among ABC1 voters, who include managerial, administrative or professional workers.
The Labour Party has sunk to attracting just 24 per cent of middle class and 26 per cent of working class voters.
If you want to find the new dividing line in British politics, age is the new predictor. Generally, YouGov's polling has found that the older you get, the more likely you are to vote Conservative.
Labour is 19 points ahead among 18-24 year-olds while the Conservatives are ahead by a huge 49 points among the over 65s.
