(BBC) A former national counter terrorism co-ordinator has told the BBC the government is not doing enough to ensure that venues are secure.
Nick Aldworth has warned new legislation is needed to reduce the impact of any future attack.
He is supporting a campaign for more rigorous checks at venues, under the name Martyn’s Law, after Martyn Hett, a victim of the Manchester Arena attack.
He said such a law could have prevented the spate of attacks in the UK in 2017.
At the time, Mr Aldworth was a Metropolitan Police chief superintendent in charge of keeping Londoners safe.
“People died on my watch when I was responsible for trying to keep London and, more subsequently, the UK secure,” he said.
