There is a certain steel about a mother who has lost a child.

It’s hard to put your finger on, but perhaps after going through hell you re-emerge made of a different material to the rest of us.

Figen Murray has been utterly relentless after her son Martyn Hett was killed in the Manchester Arena terror attack at an Ariana Grande concert in May 2017.

When she worried that politicians’ support was wavering last year, she walked 200 miles from the place Martyn died to Downing Street – and needed a hip replacement after.

And on Thursday, Martyn’s Law – rules to better train staff and safeguard venues against terrorists – was passed by royal assent, finally becoming law.

I sat down with Figen just before she went into Number 10 Downing Street to meet the prime minister, and she told me after six years of campaigning, the moment “feels surreal”.

She continued: “The Manchester attack was a wake up call. But it also made question, who are these people who do these things? Why are they doing it? What are governments doing about it? And I realised the only way I could get the answers was to educate myself – so I did a masters in counter-terrorism.

“I’ve recognised that people were radicalised. When you were a newborn baby, you were innocent but somebody poisoned your mind.

“There are people who try to groom young people into their ideology, and I want them to recognise where these people operate, the tricks they use, the things they say and how they can recognise themselves or others in the process of being radicalised and how to get out.”

She also supports the initiative to show the Netflix drama Adolescence in schools: “I think it’s absolutely important that young people see that programme and they learn more about it. It’s a good thing and I’m hoping they’re taking it further.”

There will be a debate – certainly – about the financial impact the legislation will have on venues, but the legislation has been welcomed by safety campaigners.

Emma Kay, co-founder of personal safety app WalkSafe which geo-fences events and stadiums, said: “The passing of Martyn’s Law is hugely progressive move that will keep young people safe on nights out.

“Our research has shown that 63% of women prefer to visit venues with safety initiatives in place. People want safer experiences and to know their friends and loved ones arrive home safely.”

When I sat down with Figen, I asked her how Martyn would feel today.

“Knowing Martyn, the party animal he was, he’d throw the biggest party ever,” she said.

“He was full of life and lived life not just at 100 miles an hour, but 200 miles an hour.

“You would definitely know when he came through the door, and he had an incredible ability to make everyone feel that they are the most important person in that moment in his life. And I really miss that.”
