Boris Johnson and Jeremy Corbyn have put election campaigning on hold to pay respects to war dead at the Cenotaph on Remembrance Sunday.
The Prime Minister and Labour leader were among thousands of people attending the wreath-laying service at Whitehall in central London.
Former PMs Theresa May, David Cameron, Gordon Brown and Tony Blair joined hundreds of military personnel, religious leaders and representatives of Commonwealth nations at the memorial.
The Queen watched from a balcony as a two minute silence was observed at 11am with the beginning and end marked by the firing of a gun by the King’s Troop Royal Horse Artillery.
Buglers of the Royal Marines sounded the Last Post before wreaths were laid at the Cenotaph by dignitaries.
The Prince of Wales will laid the first wreath on behalf of the Queen.
The Duke of Cambridge and the Duke of Sussex followed their father in laying wreaths, while their wives will also watch the ceremony from balconies.
After wreaths are laid, the Bishop of London, Dame Sarah Mullally, will lead a service of remembrance which will end with trumpeters of the Royal Air Force sounding Rouse (Reveille).
Following the ceremony, thousands of veterans and servicemen and women will march past the Cenotaph to pay their respects to those killed in past and present conflicts.
This year marks the 75th anniversary of D-Day, the Battle of Kohima in India, the Battle of Arnhem in the Netherlands and the Battle of Monte Cassino in Italy.
In a video released on his Twitter account before the ceremony, Mr Corbyn paid tribute to the work of the Armed Forces both current and throughout history.
He said: ‘We remember the many brave people from Britain and all across the world who put their lives on the line making huge sacrifices in two world wars which cost the lives of millions, and in all other conflicts since.
‘And we stand together to say: Never again.’
