Speaking at FMQ's today, Scottish Liberal Democrat leader Willie Rennie said:
"For four years I would walk up Kennington Road and over Westminster Bridge. I’d look up to Big Ben then down the Thames. Dodging past the tourists taking pictures of this iconic scene recognised across the globe. I would descend the steps and into the Palace of Westminster nodding at the police officer who would nod in return. Morning, Mr Rennie. The personal touch.
"I don’t think I will be able to walk that route again without thinking of the people run over. The woman in the river. The people and the police officers injured. The three people who died – perhaps they were tourists taking pictures. The officer who stood to defend democracy, losing his life. But I do want to be free to walk that route again.
"We must do all we can to protect our open, free and liberal society. Never generalising. Never stigmatising. Reaching out to all faiths, religions, countries and creeds. Although the attacker yesterday was born here his violent ideology is one that pervades the globe. That is why we must act together with our partners wherever they are in the world."
