Not the first attack on The Canary from the usual suspects.
"One of its first targets was The Canary, a pro-Corbyn website that was achieving 8.5 million hits a month.
Working closely with the anti-Corbyn Jewish Labour Movement, the book says McSweeney secretly recruited Countdown co-presenter Rachel Riley to front a campaign targeting The Canary’s advertisers with claims the outlet was antisemitic.
The Canary was later cleared by the independent regulator Impress (a fact Pogrund and Maguire don’t mention), but the damage was done. The Canary “went down from 22 staff to one member of staff within a few months of us targeting it,” SFFN crowed.
“Bye bye Birdie!!!” tweeted Rachel Riley."
