PC Keith Palmer, who was stabbed to death during the Westminster terror attack, and PC Charlie Guenigault, who was severely injured while protecting the public during the London Bridge attacks, have been honoured for their bravery.
The two Metropolitan Police officers shared first prize at this year's Police Bravery Awards ceremony at Downing Street.
Earlier this year, PC Palmer, who was stabbed as he guarded the Houses of Parliament after terrorist Khalid Masood ran over dozens of pedestrians on Westminster Bridge on 22 March last year, was posthumously awarded the George Medal, the second highest award for gallantry.
PC Guenigault was out with friends after his shift and was on his way home when the London Bridge attackers ploughed a van into pedestrians before indiscriminately stabbing people at Borough Market.
Despite being unarmed, he ran towards them and was stabbed in the head, back and stomach.
Calum Macleod, chair of the Police Federation of England and Wales which hosts the awards, said: "Today we commemorate true heroes.
"PC Keith Palmer paid the ultimate sacrifice for his bravery, but thanks to him many, many more deaths were prevented that day.
"For PC Charlie Guenigault, there was no such thing as 'off duty'.
"He ran towards a situation that most of us can't even imagine, putting himself in grave danger and thinking only of helping others."

He added: "These awards are a chance to showcase the exceptional bravery that officers protecting our country show day in, day out.
"The heroic deeds we have heard about today did not happen by accident; they were borne of dedication, selflessness and an overwhelming commitment to keeping the public safe."
