Mr Driver, now 92, said the war had been "quite frightening" to endure as a child, but that he felt lucky to stay with his parents throughout the conflict.Mr Driver's father was a plumber at Stone House Hospital in Kent, a mental illness treatment facility, so could not enlist in the military as he needed to be available in case it was bombed or hit by explosives.

"The work he was doing was essential for the operation of the hospital, and they had to deal with people who were very scared and could not understand what was happening," said Mr Driver.With his father around, he said there was "a better sense of security at home because the family was not split up".The Drivers had planned for their son to be an evacuee, and Gordon remembers being taken to the registration centre "dressed up and labelled as an evacuee with my mask which made you look like a frogman".

He found the centre "quite frightening" because he was entering the unknown and there was a lot of noise and activity."All of a sudden mum tugged me and said 'you're not going. I've just decided I'm going to keep you here at home'."

Mr Driver has clear memories of gathering with the family's neighbours in an air raid shelter dug by the local men.

"They put an electric light inside and it was made homely, with carpets and cushions and all the things you needed, like food, bread, milk and things to drink", he said.The guidance from 2013 "needs updating", he said, adding: "Teachers are worried about what they have the power to do when they are faced with violence in schools."

A bag search can endanger a teacher's safety, he said, and can only search pupils when authorised by a school head. "This could all mean it needs to be done by a security professional," he said, adding schools do not have funds to employ them.Butler called for "stronger deterrence", calling for carrying a weapon to "result in automatic exclusion".

"After all, it is a criminal offence and should be dealt with robustly," he said.In the Senedd on Wednesday, Conservative Senedd education spokeswoman Natasha Asghar said Welsh government guidance said carrying a weapon "no longer applies as a reason for exclusion" in schools.
