An Insulate Britain protester arrested for blocking the M25 is the wife of a Transport for London director, it has been revealed.
The Daily Mail reports that Cathy Eastburn, 54, has vowed to 'unleash hell' on drivers even though her husband is public transport boss Benedict Plowden, 58.
Ms Eastburn has been arrested several times during M25 blockades with fringe group Insulate Britain and for other activities with Extinction Rebellion.
Her antics recently became the subject of a High Court injunction by TfL which means she could be jailed if she attempts to join a blockade again.
And £170,000-a-year Mr Plowden, who was charged with the Covid Restart and Recovery Scheme, has also been accused of 'harbouring' another eco-extremist in the South London home the couple share.
The arrangement has been called 'staggeringly inappropriate', The Sun reported.
Cambridge philosophy graduate Ms Eastburn has become one of Britain's most prolific climate change activists. In December 2019 she avoided jail for gluing herself to a train in London.
She was sentenced for halting Docklands Light Railway services at Canary Wharf station in east London as part of a series of protests carried out across the city.
Eastburn was given a 12-month conditional alongside Mark Ovland, 36, and Luke Watson, 30, who both took part in the demonstration with her.
The trio had denied the charges of obstructing an engine or a carriage using a railway on April 17 this year, claiming the stunt was justified because of the threat of climate change.
Sentencing them at Inner London Crown Court, Judge Silas Reid warned against protesting that would amount to them committing further criminal offences.
But she was apprehended four times in nine days as protesters from the campaign group blocked London's Orbital Motorway last week.
But even the sound therapist was surprised by the lack of police action. While protesting she set her out-of-office email to: 'If you’re reading this, it is because I have been arrested and possibly put in prison on remand.'
But Ms Eastburn was released without charge without being interviewed each time she was arrested.
She told the Sunday Times she thought her actions were 'proportionate' because forcing drivers to sit in traffic for hours was 'incomparable to the kind of chaos that's coming down the track - major flooding and major food shortages'.
Mr Plowden meanwhile has been tasked with 'getting London moving after the pandemic', though last night it emerged he was leaving his post.
He has held a number of senior roles at TfL since joining in 2004, including Director of Borough Partnerships and Director of Strategy and Planning in Surface Transport.
Mr Plowden does have his own green credentials as well, described as a 'leading environmental campaigner' he founded climate group Living Streets which works to create a better walking environment across the country.
The £1.5million South London home he shares with Ms Eastburn is believed to have been used by activist David McKenny, 38, with whom Ms Eastburn pledged to 'unleash hell' on innocent drivers in the run up to next month's COP26 climate summit.
Last night the couple were blasted by Tory MP and transport select committee member Greg Smith.
'Insulate Britain has caused untold misery for individuals and businesses over recent weeks,' he told The Sun.
'It is an absolute kick in the teeth that someone senior in TfL — an arm of the British state — has been harbouring them in their house. This is unacceptable.'
London mayor Sadiq Khan, who oversees TfL, has previously accused Insulate Britain of risking people lives on busy roads.
