Gabon and Togo joined the Commonwealth on Saturday, becoming the latest nations with no historic ties to Britain to enter the English-speaking club headed by Queen Elizabeth II.

The 54-nation group of mostly former British colonies accepted Togo and Gabon's application for membership on the final day of its leadership summit in Rwanda.

"We have admitted Gabon and Togo as new members, and we all welcome them to the Commonwealth family," Rwandan President Paul Kagame said at the closing press conference.

The French-speaking West African states are the first new members to join the Commonwealth since Rwanda in 2009.
