The increased measures to protect the public come just 24 hours after seven people were killed and 48 injured in a terror attack in London Bridge and Borough Market.

The white van used in the attack was able to reach speeds of more that 50mph before it was driven into victims on the bridge.

The three male attackers then jumped out of the vehicle and stabbed people with foot-long knives.

It has been reported that London's municipal governing body, City of London Corporation (COLC), ruled out installing anti-terror bollards in the London Bridge area just 24 hours before the attack.
