The poll puts the Opposition on the same level as they secured at the last general election when Jeremy Corbyn was leader. In a further blow for the party, Sir Keir Starmer's personal popularity has also taken a hit over the past week with 15 percent more people believing Mr Johnson would make a better Prime Minister.
Pollsters YouGov surveyed 1,715 Brits between March 3 and 4.
If a general election was held tomorrow, 45 percent of those polled would vote for the Conservatives, up four percent on a similar survey a week ago.
Labour would pick up 32 percent of the vote, the same amount as in the December 2019 election.
The result at the polls was the party's worst since 1935, with Labour winning just 203 seats.
The mega-boost for the Conservatives comes ahead of crunch votes in May which will see Brits go to the ballot box for a series of local council and mayoral elections, as well as the Scottish and Welsh parliament elections.
It also comes despite Chancellor Rishi Sunak announcing a Budget yesterday in which he pledged to hike up taxes over the next four years.
The Chancellor warned yesterday he was planning £65billion in tax rises to pay for the cost of keeping the economy afloat during the pandemic.
His measures include millions paying more in income tax after he froze the tax-free allowance at £12,500 and the higher tax rate threshold at £50,000.
Mr Sunak also said corporation tax would be hiked up from 19 percent to 25 percent from 2025.
The Conservative MP said while supporting jobs was his priority during the coronavirus crisis, once Britain is able to end social distancing restrictions he will have no choice but to raise taxes.
He said: "Once we are on the way to recovery, we will need to begin fixing the public finances – and I want to be honest today about our plans to do that."
His message appears to have been overwhelmingly supported by the public with 55 percent of voters saying the Budget was "fair" - the highest rating recorded in 12 years.
