In 1984, International Marxist Group (a loose band of Hampstead socialists, student revolutionaries and former communists) asked one its associates about the weather for that winter.

Britain’s coal miners were planning a strike and their far-Left allies wanted to know whether it would be cold enough for their action to be effective — in other words, if they could bring the country to its knees.

Piers Corbyn was an amateur meteorologist turned astrophysicist, and had also developed a method for solar-based weather forecasting.

He concluded by presenting his evidence before a National Union of Mineworkers Committee. Yes, it was going to be very cold.

NUM members were very grateful and Arthur Scargill, one of the leaders of the group, rang Corbyn later to inquire how long it would last. It might be long enough for Margaret Thatcher’s Tory government to fall, he was informed.

Corbyn’s prediction about the weather was true enough — the winter of 1984-85 was unusually cold. However, Mrs Thatcher was able to overcome the strike and revive the economy, changing British industrial relations.

Today, 38 years later, PiersCorbyn’s name has been associated with another set of protests. He is also the front man for the anti-vaccine campaign. His cause is far worse and more dangerous than the strike by the miners that threatened to shut down the country’s electricity.

For this movement, fuelled by conspiracy theories on social media, endangers every one of us by spreading fear and disinformation — and everyone who consequently fails to get vaccinated reduces our ability to control the pandemic effectively.

The boffin with crooked teeth and scruffy hair, once dismissed as former Labour leader Jeremy Corbyn’s harmless if eccentric older brother who made a living from betting on the weather, is the high priest of these protesters — a rabble of Covid-deniers, anti-lockdown fanatics and ‘anti-vaxxers’.

The campaign got a more sinister twist when Corbyn led a group invaded Milton Keynes to test for coronavirus. This was followed by shouting abuse at panicked staff.

Social media shared videos of protesters taking control of the centre for walk-through testing while shouting “shame on You” at the staff.

The site was filmed by placard-waving protestors, who were seen marching around the area and throwing traffic cones at each other. The staff were forced to hide and are accused of being “fascists”, “cowards” or “murderers”.

Film footage showed one protester taking a bag of test kits and equipment out of a marquee. Then, she used a plastic container as a handle to carry them off. After she was done, the footage showed her dumping the material in a trash can outside the centre.

Corbyn (74), was not among the people filmed on site, but could be heard using a megaphone. ‘We are peaceful. He said, “You’re killing people.” He declared that the Covid vaccine was bio-weapon, and accused employees of playing Russian Roulette with humans.

Spouting such claptrap has elevated him to a place alongside his fellow zealots in the movement, who include David Icke — the serial conspiracy theorist who believes world events are determined by shape-shifting reptilians — and Kate Shemirani, a former nurse who outrageously compared NHS workers to Nazi war criminals. They have all addressed anti-vaxxer protests at various points.

These extremists include the British branch of QAnon as well as extreme Right-wing supporters of Donald Trump. There are also anti-5G technology campaigners.

Piers Corbyn believes that the pandemic was a hoax. The Government claims it wants to establish a “new order” through the use of lockdowns.

He led a group of anti-vaxxers who compelled a Brighton vaccination center to stop working.

In one stroke, he demonstrated that Labour’s previous leader was not the sole Corbyn to exhibit a shocking lack of judgment.

He said to supporters, just days before Christmas: ‘We need to kill those scum. Those scum have made the decision to introduce new fascism. It’s necessary to compile a list. . . If your MP is among them, you should go to their offices. I recommend that they be burned down.

Police acted a day later after the brazen provocation. Corbyn was charged with encouraging arson.

Priti Patel, Home Secretary has pledged a police investigation of Corbyn and his mob for their invasion at the Milton Keynes Test-and-Trace Centre. She declared that she was ready to support the police in taking swift action.

Corbyn, however, is free to keep selling anti-vax propaganda to his unstable, unpredictable supporters.

At the time vaccines were being developed, they were considered fringe elements. This is not true anymore, thanks to Corbyn’s friends. They have “weaponized” the pandemic, and they succeeded in instilling doubts about vaccines in many minds.

Week after week, Corbyn has taken his incoherent, hate-filled message around the country — and has gained support.

For a man proud of his physics heritage — he graduated with a First from Imperial College and took a masters at Queen Mary College — some of his claims are not just nonsensical but unscientific.

They are still insignificant when compared to the mounting rhetoric from his Stop New Normal campaign.

The leaflet that he wrote compared Covid-19’s response to Nazi concentration camp experiments.

This was illustrated by the famous Auschwitz inscription, which changed the meaning of Arbeit macht frei (“work makes you free”) to “vaccines are the safest path to liberty”.

There was also the time given to the ambitious-sounding Centre for Research on Globalisation. This was actually funded by a conspiracy theorist who claimed that 9/11 was a conspiracies.

Piers Corbyn, who has been a major speaker and organizer for the anti-vaccine brigade since August 2020, is now a street activist with the same passion he showed when he was “manning the barsricades” for London’s 1970s squatting campaigns.

In fact, Corbyn, one of four boys born into a Labour-supporting family — his father was an engineer and his mother a science teacher — seems to have spent all his life trying to be noticed, taking part in gimmicky escapades such as the 1975 showdown in Elgin Avenue, when he and 200 squatters occupied three rows of old houses in Maida Vale, West London.

He was certainly noticed. This same desperate need for attention was evident in the protest he held last New Year’s Eve near London’s busy St. Thomas’ Hospital.

He finished his performance by lighting a fire and haranguing passers-by.

He was spitting out an inflammable liquid that ignited, and someone was there to record it.

As his eccentric crackpots continue to travel the country, his tour has not slowed down. They have visited every corner of the UK, including Liverpool, Manchester Sheffield, Nottingham and Cardiff.

Everywhere the message is the same: mass vaccination — which governments and global experts believe is the only way out of contagion and lockdown — is a fraud, and the vaccine itself is a ‘satanic death shot’.

The yellow T-shirt he wore with his slogan “resist, challenge, do not obey” was worn by the man to High Streets, Shopping Centres, and Undergrounds. There he and his friends filmed a song-and dance routine TikTok-style with annoying lyrics.

It is far from Corbyn’s rural childhood in Chetwynd Aston (Shropshire), where he grew up on a Georgian estate with his family. Here, Corbyn and his siblings enjoyed the outdoors playing bicycle polo.

Theirs was a privileged upbringing of prep schools and a selective and now fee-paying grammar — awkward for such committed Left-wingers.

Piers chose Physics, while his elder brother was a Concorde flight test specialist and the other a mine engineer.

As baby brother Jeremy was cutting his teeth in the world of politics, Piers was being photographed — in his academic gown — with the Queen during a royal visit to Imperial College.

After completing his MSc degree in Astrophysics, it was 1969. He also became a political activist before becoming a climate change-sceptic meteorologist.

Piers Corbyn doesn’t have a reset button, unlike his brother who was able to use an allotment or children as distractions from radical politics. He is an isolated man who doesn’t have children. Marion Roberts was his former wife, but he appears now to be living alone in South London in an apartment near Old Kent Road. That is the location where he was taken into police custody in the hours following his ‘burn all the MPs’ tirade.

Piers Corbyn is adamantly against criticism, and shunned from former political allies. He seems completely at ease in the company conspiracy theory fanatics.

He is a liar and misinformator. It’s time to face him, or change the law. Of course, he is entitled to believe what he wants. The punishment for inciting fear and spreading dangerous propaganda should be harsh and swift: jail.
