Labour's campaign coordinator Andrew Gwynne says the party has collected several examples of how Labour's leaders received "negative treatment, harsher scrutiny and angular editorial comments" than the one received by Prime Minister Boris Johnson's Conservative Party.

"If the Conservatives are allowed to" play "or manipulate the BBC, and this behavior continues uncontrolled, the company has been complicit in giving the Conservative party an unfair advantage in the election," Andrew Gwynne wrote in a letter to the BBC's director general Tony Hall.

Labor is lagging behind

Labor is currently behind the Conservatives in opinion polls and the party is particularly unhappy that Boris Johnson will not be interviewed by seasoned journalist Andrew Neil, something that all other party leaders have done.

In a comment on the letter, a public service channel representative said:

"The BBC will continue to make its independent publicist decisions, and is determined to report on the election campaign fairly, impartially and without fear of favoring it."
