TWO MPs from Cornwall and Devon were caught up in a lockdown of Parliament while a terrorist attack unfolded in Westminster.

MP for North Cornwall Scott Mann was in the House of Commons chamber during the vote as the attack took place.

Once news of the attack broke inside Westminster, Commons business was suspended and the MPs were kept in the chamber. The building went into lockdown and MPs and their colleagues were told to remain in their offices.

A member of Mr Mann’s parliamentary team told the Post: “Our office is next to Westminster Bridge, and although we didn’t see anything, we did hear a scream and a splash, which presumably was the woman who jumped or fell into the Thames.

“Initially we thought it was a minor accident or someone who had jumped into the water, but the reaction of members of the public, the quick presence of police and the suspension of business made us realise it was worse.”

They added: “We had to remain in our office until 5.45pm when we were moved to Westminster Hall along with a couple of thousand people — a mix of staff and visitors.

“Scott and the other MPs were also allowed into Westminster Hall, and we were allowed to leave at 7.30pm.”

Geoffrey Cox, MP for Torridge and West Devon, was also in the House of Commons chamber as the terror attack in Westminster unfolded.

He has paid tribute to the emergency services, the Metropolitan Police and Parliamentary authorities for their rapid response and for the safety and assurance they offered his Parliamentary colleagues and office.

He said: “As I reflect on the atrocities committed in the heart of our democratic institutions, I am proud of the exemplary response of our police, security and emergency services.

“I pay tribute to them for discharging their duties so faithfully and coming swiftly and effectively to the aid of those who needed medical attention. The exceptional sacrifice made by PC Keith Palmer who gave his life in the service of his country while doing his duty is an example of the highest standards of conduct of our police and armed forces.

“I am deeply saddened by the loss of life and express my deepest sympathies to those families who lost loved ones and my fervent wishes for the speedy recovery of those who are injured.”

Detectives from the Metropolitan Police’s Counter Terrorism Command have now confirmed that the terrorist attack was over within 82 seconds.

Five people were killed, including the attacker, and at least 50 people were injured with 31 requiring hospital treatment as the attack unfolded.
