Liberal Democrat leader Tim Farron has lamented the re-election of Jeremy Corbyn as Labour leader, describing him as a "failed" opposition leader.
Mr Farron added that his party is prepared to provide opposition to the "Conservative Brexit Government" if Labour doesn't "do its job".
"This is a case of things can only get worse," he said. "Jeremy Corbyn has failed as opposition leader and failed to stand up for Britain's place in Europe.
"He is now not backing our membership of the single market despite the damage leaving would do to our economy and the threat it poses to jobs.
"After a year of failure, it is disappointing for all of those who oppose this Government that the Labour leadership will continue to be dominated by ineffectual leaders.
"As Labour fight among themselves the Liberal Democrats will make the case for an open tolerant and united Britain.
"If Labour won't do its job as the opposition to the Conservative Brexit Government, we will."
The ComRes survey for the Sunday Mirror and Independent found just 16% of voters thought Labour was likely to win the next election.
The Labour leader insists there is party unity on policy, but it appears he doesn't want his former opponents back in his top team.
In what is his first engagement after being reaffirmed as party leader, Jeremy Corbyn remembered a 'brave woman who stood up for everybody'.
