Ofcom have dismissed every complaint of bias over broadcast coverage of Jeremy Corbyn since he became Labour leader.

The independent media watchdog, which regulates broadcasters including Sky News, Channel 4 and ITV - but not the BBC - said none of the complaints indicated breaches of their rules.

According to figures obtained by Politics Home , Ofcom dismissed 71 complaints of bias since September 2015.

Many Corbyn supporters - and the Labour leader himself - have complained he wasn’t given a fair crack by broadcasters, particularly in the early months of his leadership and the days following the EU referendum .

Ofcom’s rules say “due impartiality” must be maintained in all news coverage.

That means issues must be presented in a fair and balanced way, and include various views and arguments.

But it does not require broadcasters to give equal time to each view or side of the argument.

There were 23 complaints about Channel 4, 12 about ITV and 31 about Sky News.

But Ofcom dismissed claims of bias, saying: “After careful assessment of the complaints and the broadcast material, Ofcom did not identify any issues which warranted further investigation under its rules.”

The Corbyn re-election campaign refused to take part in a leadership hustings with Channel 4, saying they were not “impartial”, though he did agree to a debate with rival Owen Smith hosted by Sky News.

Seven of the complaints against Channel 4 related to their Dispatches documentary in September, which focused on Corbyn’s re-election campaign and supporters’ group Momentum.

In July, Mr Corbyn blamed a “ludicrously biased” media for a “systematic undermining” of his leadership.

A study by the London School of Economics’ department of Media and Communications said 57% of all print news stories about Mr Corbyn were "antagonistic" or "critical in a measured but even-handed manner... something we would expect from the media".

The rest were either neutral or postive.

The study also said 44% of stories about Mr Corbyn quoted him in his own words and 23% quoted pro-Corbyn Labour sources.
