Commonwealth Heads of Government Meeting ( CHOGM ; or ) is a biennial summit meeting of the heads of government from all Commonwealth nations . Every two years the meeting is held in a different member state and is chaired by that nation 's respective Prime Minister or President who becomes the Commonwealth Chair-in-Office until the next meeting . Queen Elizabeth II , who is the Head of the Commonwealth , attended every CHOGM beginning with Ottawa in 1973 until Perth in 2011 , although her formal participation only began in 1997 . However , she was represented by the Prince of Wales at the 2013 meeting as the 87-year-old monarch was curtailing long distance travel . The Queen attended the 2015 summit in Malta and the 2018 CHOGM held in London
