In an effort to protect the Group's income, its managing director/Chairman, Lord Ashfield, lobbied the government for regulation of transport services in the London area. During the 1920s, a series of legislative initiatives was made in this direction, with Ashfield and Labour London County Councillor (later MP) Herbert Morrison, at the forefront of debates as to the level of regulation and public control under which transport services should be brought. Ashfield aimed for regulation that would give the existing Group protection from competition and allow it to take substantive control of the LCC's tram system; Morrison preferred full public ownership. Eventually, after several years of false starts, a bill was announced at the end of 1930 for the formation of the London Passenger Transport Board, a public corporation that would take control of the Underground Group, the Metropolitan Railway as well as all buses and trams within an area designated as the London Passenger Transport Area. The Board was a compromise – public ownership but not full nationalisation – and came into existence on 1 July 1933. On this date, the C&SLR and the other Underground companies were liquidated.
