Lord Mayor of London

The Lord Mayor of London is the City of London's mayor and leader of the City of London Corporation. Within the City, the Lord Mayor is accorded precedence over all individuals except the sovereign and retains various traditional powers, rights and privileges, including the title and style The Right Honourable Lord Mayor of London.

The Lord Mayor is elected at Common Hall each year on Michaelmas, and takes office on the Friday before the second Saturday in November, at The Silent Ceremony.

The Lord Mayor's Show is held on the day after taking office; the Lord Mayor, preceded by a procession, travels to the Royal Courts of Justice at the Strand to swear allegiance to the sovereign before the Justices of the High Court.

Elections
The Lord Mayor is elected at Common Hall, comprising liverymen belonging to all of the City's livery companies. Common Hall is summoned by the sitting Lord Mayor; it meets at Guildhall on Michaelmas Day (29 September) or on the closest weekday. Voting is by show of hands; if, however, any liveryman so demands, balloting is held a fortnight later.
The Lord Mayor is then sworn in November, on the day before the Lord Mayor's Show. The ceremony is known as the "Silent Ceremony”

Lord Mayor’s Show
The day after being sworn into office, the Lord Mayor leads a procession from the City of London to the Royal Courts of Justice in the City of Westminster, where the Lord Mayor swears allegiance to the Crown. This pageantry has evolved into one of London's longest-running and most popular annual events, known as the "Lord Mayor's Show".
Nowadays, this festival combines traditional British pageantry with the element of carnival, and since 1959 it has been held on the second Saturday in November. Participants include the livery companies, bands and members of the military, charities and schools. In the evening, a fireworks display is held.
