The Green prospective parliamentary candidate for North Thanet, Ed Targett, has offered free self-defence classes to his rivals.
The pledge comes after he received 14 pages of personal security advice from counter-terrorism police.
The dad-of-three said: “I was taken aback to get posted a guide to personal safety from the National Counter Terrorism Security Office last week.”
The 34-year-old regularly boxes on local boxing shows and has raised money for Kent Air Ambulance and The Soldier’s Charity.
He added: “It took a moment to click why I’d received it. I only realised when I saw my nomination papers underneath confirming me as a parliamentary candidate.”
The guidebook was posted to parliamentary candidates nationwide.
Also posted was a letter from the Met Police’s deputy assistant commissioner Lucy D’Orsi.
In it she warns: “The UK threat level remains at SEVERE, meaning an attack is highly likely.”
The security warning follows the murder of Jo Cox MP on June 16 last year by right-wing extremist Thomas Mair, and the Westminster knife attack in March by Islamic extremist, Kent-born Khalid Masood, which left four dead.
Mr Targett, said: “I’d barely announced my campaign before I had abusive comments rolling in on Facebook. I can imagine the other candidates get it a lot worse. Nobody deserves to feel threatened for getting out and exercising their democratic right.”
“The offer’s a bit tongue-in-cheek. But I want to draw attention to the threats parliamentary candidates receive and the need to keep political debate civil.
“If any of my rivals would like free boxing or ju-jitsu lessons I’ll happily sponsor them to come and train at my local club in Margate.”
