The 34-year-old royal honoured the police officer who was stabbed by Khalid Masood during the terrifying ordeal, which took place outside the Houses of Parliament on Wednesday 22, with a wreath at the police memorial at the National Memorial Arboreteum in Staffordshire.

According to BBC News Prince William attached a hand-written note to the display praising Keith and everyone who has served for the community "so valiantly".

It read: "For PC Keith Palmer and all those who have served our community so valiantly; your legacy is our way of life. William."

And William - who has three-year-old son Prince George and 22-month-old daughter Princess Charlotte with his wife Catherine, Duchess of Cambridge - officially opened the new remembrance centre, during his visit on Wednesday (29.03.17).

William, who is a patron of the National Memorial Arboretum Appeal, met with veterans of all three armed services at the official opening of the new centre, while he will also meet with volunteers and schoolchildren.

And he also unveiled a commemorative plaque before he visited the Landscapes of Life exhibition at the centre, which has an audio guide to divulge information about the 61-acre site's 330 memorials that are dedicated to everyone who has been a part of the armed forces, the emergency services and civilians.

Meanwhile, Acting Met Police Commissioner Craig Mackey has urged people living in London to "come together" and talk about how great England's capital city is in the wake of the horrific ordeal.

Speaking previously, he said: "Our thoughts, our prayers, go out to everyone who was affected by the events last week.

"I would urge you, if you get time, to go on to the bridge, talk to Londoners, talk and get a feel for this great city and how it's come together in responding to these events."
