Jeremy Corbyn's conspiracy theorist brother Piers addresses crowds at protest against masks, vaccinations and 5G outside Welsh Parliament - as demonstrators declare 'Covid is a hoax'

Piers Corbyn has addressed crowds at a protest against masks, vaccinations and 5G outside Welsh Parliament.

The brother of former Labour leader Jeremy Corbyn addressed dozens gathered on the steps of Welsh Parliament in Cardiff on Sunday.

Mr Corbyn, 73, wielded a microphone in front of a large banner declaring 'End all Covid Vax' and 'Take down 5G'.

Several dozen people appeared to be attending the anti-lockdown rally, according to images of the protest.

The crowds, who were not wearing face masks, brandished banners and placards reading 'Covid is a hoax', 'Freedom from tyranny' and 'Free your face'.

It comes after the weather forecaster told his 38,000 Twitter followers on Saturday that police warned him that he could be arrested if he travelled to locked-down Cardiff. 

The divisive anti-lockdown campaigner wrote: 'I'm going. DEFY THEM! GO in huge numbers *£FreeCardiff*'

South Wales Police told MailOnline that three people had been 'reported for summons' over the rally.

New coronavirus restrictions came into force in the Welsh capital on September 27 after a sharp rises of cases in the area.

People are not allowed to enter or leave the Cardiff council area without a reasonable excuse, according to the government website.

Residents are also restricted from meeting indoors with anyone who is not part of their household or form an extended 'bubble' without a good reason. 

The government regulations allow up to a maximum of 30 people to meet outdoors, but they must all live in the Cardiff council area and social distancing must be adhered to.

South Wales Police said that two men and a woman who attended the rally have been 'reported for summons for breaching Covid-19 restrictions by entering Cardiff without reasonable excuse'.

 Mr Corbyn has recently addressed several rallies similar to Sunday's Cardiff protest in recent weeks, including joining crowds at a large protest in Trafalgar Square, London

A South Wales Police spokesperson added: 'South Wales Police was made aware of a planned protest relating to the current Covid-19 regulations by Stand Up X Anti Lockdown Movement.

'Officers worked to engage with protest organisers and attendees in order to remind them of their obligations under the current Coronavirus legislation, and the overarching goal for everyone to take personal responsibility by following Welsh Government regulations to Keep Wales Safe.

'We are duty-bound to take into account all relevant legislation, and South Wales Police has strived to maintain a consistent policing style of engaging, explaining and encouraging, and enforcing as last resort where necessary, throughout this public health emergency.

'This approach was maintained throughout the event.

'Two men and a woman who attended today's event have been reported for summons for breaching Covid-19 restrictions by entering Cardiff without reasonable excuse.

'It is unacceptable and extremely disappointing that people have flouted the rules by travelling into Cardiff and gathering in large numbers.

'Enquiries are continuing and further action against other individuals is anticipated once all evidence has been considered.'

Mr Corbyn has recently addressed several similar rallies and was charged under coronavirus legislation over a pre-planned illegal gathering in Sheffield city centre last month.

He was bailed to appear at Sheffield Magistrates' Court in November.

The conspiracy theorist has appeared at rallies in numerous cities across recent weeks, including in Nottingham, Oxford and London.

Mr Corbyn joined anti-lockdown protesters when at least 15,000 demonstrators descended on Trafalgar Square last month.

Attendees of the 'We Do Not Consent' rally ditched their masks as they crammed into the London square, despite Metropolitan Police pleading with people to stick to Britain's coronavirus rules.

Sixteen people were arrested during the demonstration - which later moved to Hyde Park - and nine police officers were injured with two rushed to hospital.

Mr Corbyn was among the crowd alongside 68-year-old conspiracy theorist David Icke, who has made a series of false claims linking Covid-19 to 5G technology.

In a statement, Scotland Yard said the breach had 'put people in danger of transmitting the virus' which voided their risk assessment and left those at the event 'no longer exempt' from Covid-19 restrictions.

Skirmishes broke out between protesters and police later in the day, with those in attendance chanting 'shame on you' - shoving at officers as they passed through the crammed crowd.

The meteorologist was also handed the first £10,000 fine in London for an illegal gathering in August after he organised a march claiming coronavirus is a hoax. 

He led more than 10,000 anti-lockdown protesters at the 'Unite for Freedom' rally in Trafalgar Square on August 29.

He was among eight other offenders who were fined across the rest of England under the lockdown measures at that time, designed to stop gatherings of more than 30 people.

The arrest of Mr Corbyn in Trafalgar Square was the third time the divisive anti-lockdown campaigner has been arrested since the pandemic started. He was carted out of Hyde Park by officers on May 16 and May 30. 

Mr Corbyn has previously made unfounded links between the 5G and Covid-19, calling the pandemic a 'pack of lies to brainwash you and keep you in order'.

There is no evidence linking the super-fast internet technology and coronavirus, with scientists fearing that a rise in measles among children can be attributed in part to unfounded fears about vaccines. 

Conspiracy theorists have made baseless claims that the burgeoning 5G internet network is behind the coronavirus outbreak.

They have claimed that towers could emit dangerous radiation in a misinformation campaign that has seen some towers vandalised and set on fire.

Vaccines are the most effective way to prevent infectious disease and have virtually eradicated smallpox, polio and tetanus in the UK, according to the NHS.

But if people stop getting vaccinated then diseases can quickly spread again, the health service said.

There is no evidence that vaccines cause autism, allergies or other conditions, weaken the immune system in any way, or contain harmful ingredients.
