Keir Starmer's poll ratings are now worse than Jeremy Corbyn's at the same point in their respective leaderships, polls show.
21 per cent of voters then believed Mr Corbyn was doing well while 61 per cent thought he was doing badly.
Mr Corbyn had by this point survived an attempt by internal opponents to oust him as leader, winning the 2016 leadership contest by 62 per cent to 38 for his rival Owen Smith.
The dire comparison is a blow for Sir Keir, whose pitch to Labour members centered around the idea that he would be more popular with voters than Mr Corbyn.
But his approach has so far failed to bear electoral fruit, with Labour last week losing a slew of council seats across the country last contested under Mr Corbyn.
An embarrassing parliamentary by-election defeat in Hartlepool, a seat Labour won in 2017 and 2019, has also sparked a wave of criticism, as has his handling of an ensuing reshuffle.
A source who was close to Jeremy Corbyn's leadership told The Independent: "Keir is proving the old adage right that if you stand for nothing, you'll fall for anything.
"Jeremy's ratings were low at this point after a year of being savaged by the media and his own MPs. Keir's had a softball ride.
"Unless Starmer develops a backbone, shows people what he's about and what his alternative for the country is, his ratings will fall further in an election rather that rise dramatically like Jeremy's did."
Keir Starmer's team did not respond to a request for comment on the poll findings.
Labour sit as far as 10 points behind the Conservatives in the voting intention polls for the next general election, according to the latest surveys.
