The 93-year-old monarch pursued the service from the balcony of the Foreign & Commonwealth Office when her son Charles, the Prince of Wales, laid a wreath for her.

The ceremony is an annual Sunday service that is closest to November 11, the day the 1918 World War ended.

A two-minute silence was also observed to remember the dead when Big Ben struck at 11am.

British Prime Minister Boris Johnson and Labor Opposition Leader Jeremy Corbyn also attended the ceremony and wreathed wreaths during the election campaign.

The Royals also paid tribute on Saturday night at the Royal British Legion Festival of Remembrance at the Royal Albert Hall.

The memorial service, hosted by the Royal British Legion, was the 75th anniversary of the key battles of 1944, including Monte Cassino, Kohima, Imphal and D-Day, highlighting in particular the role of the Commonwealth and the Allied Forces.

It also celebrated the 100th anniversary of the Government Communications Headquarters (GCHQ) and honored the company of RFA Mounts Bay, which contributed significantly to the transportation of supplies and relief supplies to the Bahamas following Hurricane Dorian in September.

Meghan, Duchess of Sussex, and Prince Harry, Duke of Sussex, attend the annual Royal British Legion Festival of Remembrance at the Royal Albert Hall.
The engagement was the first time that Harry, Meghan, William, and Catherine appeared in public since Harry addressed rumors of a crack with his brother in a television documentary in October.

During the week, events took place in honor of all victims of conflict. On Thursday, Meghan visited the field of memory at Westminster Abbey for the first time with her husband. The royal couple placed small crosses there to honor the dead of the war.

Earlier this week, the Queen paid a visit to the Royal British Legion Industries village in Aylesford, south east England, which provides housing and social assistance for veterans and the wider community of armed forces.
