The police officer murdered in March's Westminster attack has been awarded a posthumous bravery medal by the Queen.
PC Keith Palmer's George Medal recognises actions that "saved lives".
Gallantry awards also go to pensioner Bernard Kenny, who went to the aid of murdered MP Jo Cox, and to two men who helped after the Tunisia beach attack.
The announcements coincide with the Queen's Birthday Honours list, in which comedian Billy Connolly is knighted and actress Julie Walters becomes a dame.
Glaswegian Sir Billy, 74, who was made a CBE in 2003, said he was "pleased and a little embarrassed" to become a knight for services to entertainment and charity.
TV star June Whitfield, mezzo soprano Sarah Connolly and 100-year-old Gone with the Wind actress Olivia de Havilland also join Dame Julie as new dames.

"In doing so he made the ultimate sacrifice."
