The anniversary of the 7 July suicide bombings in London has been marked by the unveiling of a memorial in Hyde Park to those who died.
It consists of 52 metre stainless steel pillars - one for each victim. Each is 3.5 metres high.
Prince Charles led the tributes saying the date of the bombings was etched vividly on everyone's minds.
Prime Minister Gordon Brown and Minister for London Tessa Jowell joined the Prince of Wales at the unveiling of the pillars.
Relatives at the unveiling said the permanent memorial was a "fitting tribute".
In his speech, Prince Charles said he had some awareness of the loss felt by the relatives as he recalled his "deep despair" after his great-uncle Lord Mountbatten was killed in an Irish Republican Army bomb blast almost 30 years ago.
After he and Mrs Jowell addressed the memorial service, the names of the victims were read aloud and a minute's silence was observed.
The prince then laid a wreath on behalf of the nation while the Duchess of Cornwall left a floral tribute for the families.
London Mayor Boris Johnson, Conservative leader David Cameron, Liberal Democrat leader Nick Clegg, former London Mayor Ken Livingstone and senior figures from the emergency services also attended.
