Barbados ditched Britain's Queen Elizabeth as head of state, forging a new republic on Tuesday with its first-ever president and severing its last remaining colonial bonds nearly 400 years after the first English ships arrived at the Caribbean island.

At the strike of midnight, the new republic was born to the cheers of hundreds of people lining Chamberlain Bridge in the capital, Bridgetown. A 21 gun salute fired as the national anthem of Barbados was played over a crowded Heroes Square.

Prince Charles, heir to the British throne, stood somberly as Queen Elizabeth's royal standard was lowered and the new Barbados declared, a step which republicans hope will spur discussion of similar proposals in other former British colonies that have the Queen as their sovereign.
