Police and public lined the streets of central London to honour police constable Keith Palmer, 48, who died defending Westminster parliament during the March 22 terror attack.

The funeral service was held on April 11 at Southwark Cathedral, an Anglican church on the south bank of the River Thames.

The four kilometre funeral cortege began at the Palace of Westminster and ended at Southwark Cathedral.

Keith Palmer, who was married and had a young daughter, was guarding the UK parliament on March 22 when he was stabbed to death by Khalid Masood.

The dean of Southwark Rev Andrew Nunn delivered an address at the funeral.

“Keith was doing his duty, doing what he always did, and then what happened, happened,” said Rev Nunn.

“Keith laid down his life for each one of us here. And each one who have lined the streets and filled the bridges of this city today, who kept vigil last night, who gathered in the abbey last week, who laid flowers on Westminster Bridge and Parliament Square, who posted messages on social media, all who cried in front of their TVs, who listened in disbelief to their radios.”

The terror attack also claimed the lives of four other people when Masood had earlier driven a car into pedestrians on Westminster Bridge.
