Anti-terror barriers to protect Changing of the Guard at Windsor Castle

Security at Windsor Castle is being stepped up for Changing of the Guard in the wake of the Westminster terror attack.

The changes are "proportionate and necessary" but there is "no specific threat to Windsor", Thames Valley Police have said.

New barriers are being used to secure the route of the procession in addition to existing road closures.

They are being put up in time for the next Changing of the Guard on Wednesday.

Tourists flock to see the famous event, which sees soldiers in their red tunics marching through the streets accompanied by a brass band to take over guard duties at the castle.

Assistant Chief Constable Dave Hardcastle said "recent events in Westminster clearly highlight the need for extra security measures to be introduced".

"The force believes that it is proportionate and necessary to put in place extra security measures to further protect and support the public and the guard change," he said.

"This is consistent with security deployments in London.

"Preventative measures such as these have been put in place across the UK over the past 10 years at various events."

In December, after the Berlin market attack, the Metropolitan Police decided to boost security around the Changing of the Guard at Buckingham Palace.

Roads were closed and extra barriers put in place to protect the guards.

The ceremony also changed its schedule to take place on set days rather than every alternate day.
