what are freemen of the city of london
List of Honorary Freemen of the City of London The granting of the Honorary Freedom (or Freedom Honoris Causa) of the City of London is extremely rare and only generally awarded today to Royalty, Heads of State or to figures of genuine global standing. It is the highest honour which is in the power of the City of London to bestow on someone and usually takes place in Guildhall in the presence of the Common Council and with Lord Mayor, Sheriffs and Aldermen present, along with invited guests. The most recent recipient after a gap of some 11 years was Archbishop Desmond Tutu with the ceremony taking place at Mansion House on 25 November 2013. Nelson Mandela received the same honour as President of South Africa in 1996. The presentation on these occasions is made by the Chamberlain of London, and is often followed by a Guildhall or Mansion House banquet. The first historically to be so honoured was William Pitt the Elder in 1757. For many years, it was the custom to present the Freedom in specially commissioned and unique gold or silver caskets, the design of which was inspired by the background and the achievements of the individual to which it was given. More normal today would be a presentation of a scroll in an inscribed box.[citation needed]
Water supply and sanitation in London London has well developed water supply infrastructure. Most drinking water consumed in London comes from the River Thames and the River Lee. Approximately 70% of all water supplied to London is taken from the Thames upstream of Teddington Weir.[2]
