Members of the Royal Family and senior politicians have joined hundreds of war veterans to commemorate those who lost their lives in conflict as the UK marks Remembrance Sunday.

Boris Johnson, Labour leader Jeremy Corbyn and other political party leaders broke away from election campaigning to attend the service at the memorial on Whitehall in central London.

A two-minute silence was observed at 11am, beginning and ending with the firing of a gun by the King's Troop Royal Horse Artillery.

Prince Charles laid the first wreath at the Cenotaph memorial on behalf of the Queen, who watched the service from a nearby balcony.

An equerry laid a wreath for the Duke of Edinburgh, who was not present after retiring from royal duties two years ago.

Prince William and Prince Harry followed their father in laying wreaths, while the Duchess of Cambridge and the Duchess of Sussex also watched the ceremony from the balconies.

Five former prime ministers – Sir John Major, Tony Blair, Gordon Brown, David Cameron and Theresa May – were also in attendance.

After wreaths were laid, the Bishop of London, Dame Sarah Mullally, led a service of remembrance which ended with trumpeters of the Royal Air Force sounding the Rouse (Reveille).

Following the ceremony, thousands of veterans and servicemen and women began to 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.
