LONDON, Dec 10 — British Prime Minister Boris Johnson's Conservative Party has lost its poll lead over the opposition Labour Party after revelations about alleged lockdown parties at Johnson's residence provoked an outcry over hypocrisy.

A YouGov poll for The Times newspaper showed Johnson's Conservatives had lost their lead, dropping 3 percentage points from Dec. 2 to 33 per cent of the vote while Labour rose 4 percentage points to 37 per cent.

Johnson won 365 of 650 seats the 2019 snap election, the biggest Conservative Party majority since Margaret Thatcher's 1987 victory.

Johnson imposed restrictions on England on Wednesday, just hours after apologising for a video apparently showing staff laughing about a party in Downing Street during a 2020 Christmas Covid-19 lockdown when such festivities were banned.

Three quarters of people believe that there was a Christmas party in which coronavirus rules were broken and 68 per cent of those polled believe Johnson was not telling the truth when he denied it, The Times said. — Reuters
