The City of London Corporation is the governing body of the City of London, which is the historic and financial district of London. Established in the 12th century, it manages local services, including education, housing, and transportation, while also overseeing the financial and commercial activities in the area. The Corporation is unique because it operates independently from the Greater London Authority. It is led by the Lord Mayor of London, who represents the city in various ceremonial functions. The Corporation also plays a significant role in promoting the interests of businesses and maintaining the city's infrastructure.
