Richard Whittam QC, prosecuting, asked: “Do you remember hearing a man say anything?”

She replied: “He did shout something out. It was something along the lines of, ‘keep Britain independent’, or ‘British independence’.”

Describing the firearm, she said: “It was a small gun. It wasn’t a shotgun. It was a smaller gun, but it was quite deep.

Mr Whittam said: “Was Jo standing up?”She said: “Jo was lying on the floor, and she sort of tried to sit up a little bit with her right hand.

“He just started stabbing her while she was lying on the floor, stabbing her, and Jo was trying to get away.

“Fazila was shouting ‘get away from us, she has got two little children’, and I was just screaming and shouting for help.

“She couldn’t get up, but she sort of rolled over and sort of did a sideways roll and went into the road.”

Asked if the man went towards Fazila, she said: “He went towards both of us because we were quite close together at that stage.

Ms Major said: “He didn’t go very far, just a few feet and then he came back and he shot her twice more, and started stabbing her again.
