Ofcom found that none of the top 10 broke its broadcasting rules. All were on commercial channels.

The BBC has a separate complaints system and Ofcom usually only considers complaints about BBC programmes after a person has been through the corporation's own complaints system.

Last week, the BBC revealed that 12,172 people had complained that Andrew Marr's interview with Boris Johnson on 1 December was biased against the prime minister.

That was the highest number since the corporation began publishing a breakdown of complaints in the current format two years ago.

The next highest total during that time is 6,934 about BBC One's Meat: A Threat To Our Planet?, screened on 25 November, which was accused of being biased against the British farming industry.

Revealing its figures, Ofcom director of content standards Tony Close said: "Overwhelmingly, the most contentious programmes of the 2010s were either reality shows - like Love Island, Big Brother and The X Factor - or news and current affairs.

"Why is that? One important reason might be the rise of social media over the decade. We know people like to discuss reality shows online. And in a time of political change, social media has also shaped increasingly passionate debate around news coverage."
