It is painted on the wall of the depot of Tower Hamlets Parks Department.
The mural commemorates the Poplar Rates Rebellion of 1921, when Poplar Borough Council, led by former mayor George Lansbury, refused to pay precepts to London County Council, the Metropolitan Police, the Metropolitan Asylums Board and the Metropolitan Water Board, as a protest against the inequity of the system of local rates.
The campaign was widely supported by the general public and trades unions, and in due course the councillors were released from prison.
Parliament quickly passed the Local Authorities (Financial Provisions) Act 1921 to try to equalise tax burdens between rich and poor boroughs.
It has four panels, including an image of George Lansbury wearing his mayoral chain of office; placards reading "Can't Pay Won't Pay"', references reference to the campaign to abolish the 1990s era poll tax, and a list of the names of the imprisoned councillors.
