Prince Harry has laid a wreath during a Dawn Service at Wellington Arch to mark the start of Anzac Day commemorations in the UK.
Thousands of people waited in the dark before the start of proceedings, which marked 100 years since the day was first marked in London.
Anzac Day has been commemorated in the capital since the first anniversary of the Anzac landings at Gallipoli in 1916, when King George V attended a service at Westminster Abbey.
Since then, the services have become an important moment for thousands of expatriate and visiting New Zealanders and Australians, who honour the sacrifices of their countrymen and women in all wars.
Harry laid a wreath at the memorial at Hyde Park Corner, followed by the New Zealand and Australian high commissioners and other dignitaries.
He will later attend a parade at the Cenotaph, where he will lay a wreath on behalf of the Queen, and a service of commemoration and thanksgiving at Westminster Abbey.
