A coffin marked 'RIP British Empire' was thrown into Dublin's River Liffey during the Queen's funeral on Monday.
The act was carried out by Anti Imperialist Action Ireland during a protest march through the city. The move was said to have been a recreation of an action by former socialist leader James Connolly in Dublin in 1897 during a visit to the city by Queen Victoria - the late monarch's great-great-grandmother.
The group wrote on Twitter : "This afternoon, Anti Imperialist Action organised a protest march starting at the James Connolly Statue at Beresford Place and marching around to the GPO, against the grovelling worship of the English Monarchy by the Free State ruling class.
