BBC newsreaders were forced to get a police escort to the recording studio after getting stuck in London traffic, jeopardising the broadcast of the 6pm news.
News anchor Fiona Bruce and Mark Easton were in a taxi on their way to Millbank studios after a technical issue downed live shows at Broadcasting House.
In a rush to make it to Millbank the pair accidentally stumbled into the middle of a protest – grinding the traffic to a halt.
The so-called Women Against the State Pension Inequality (WASPI) had blocked the road outside Parliament, with many sitting in the street with banners preventing the traffic from passing and chanting slogans.
The BBC’s home editor, Mark Easton, tweeted a picture of him with Mrs Bruce in a taxi at 5.20pm on their way to the Westminster studios, but warned the traffic was “dreadful”.
