The Commonwealth Heads of Government Meeting 2018, also known as CHOGM 2018, was the 25th meeting of the heads of government of the Commonwealth of Nations. It was held in the United Kingdom. The meeting had been planned to have been held by Vanuatu at the end of 2017, but was moved to the United Kingdom after the impact of Cyclone Pam on the infrastructure of Vanuatu. The meeting was then postponed to April 2018 due to other international commitments.

The Commonwealth Heads of Government Meeting 2015, also known as CHOGM 2015 was the 24th meeting of the heads of government of the Commonwealth of Nations. It was held in Malta from 27 to 29 November. Sri Lankan President Maithripala Sirisena handed the position of Commonwealth Chair-in-Office to Maltese Prime Minister Joseph Muscat at the meeting.

The 23rd Commonwealth Heads of Government Meeting was held in Colombo, Sri Lanka, from 15 to 17 November 2013. Commonwealth leaders agreed on Sri Lanka as the 2013 host for the meeting when they met in Port of Spain, Trinidad and Tobago, in 2009. Sri Lanka, which was originally slated to host the summit in 2011, was accused of committing atrocities during the Sri Lankan civil war and the summit was instead held in Perth, Australia; Colombo was given the 2013 summit instead. The leaders of Canada, Mauritius, and India boycotted the summit, citing alleged human rights violations by Sri Lanka against its Tamil minority. Protests were also banned during the summit. President Mahinda Rajapaksa summarised the summit's events as: "Issues covered in the communique include development, political values, global threats, challenges and Commonwealth cooperation." However, the meeting was overshadowed by controversy over Sri Lanka's human rights record and the alleged war crimes during the final stages of the civil war. This was the first time in 40 years that the Head of the Commonwealth, Queen Elizabeth II, was not present at the CHOGM.

The Commonwealth Heads of Government Meeting 2011, commonly known as CHOGM 2011, was the twenty-second Meeting of the Heads of Government of the Commonwealth of Nations. Held in Perth, Western Australia, between 28 and 30 October 2011 and hosted by the Prime Minister Julia Gillard.

Malta, officially known as the Republic of Malta and formerly Melita, is a Southern European island country consisting of an archipelago in the Mediterranean Sea. It lies 80 km (50 mi) south of Italy, 284 km (176 mi) east of Tunisia, and 333 km (207 mi) north of Libya. With a population of about 515,000 over an area of 316 km2 (122 sq mi), Malta is the world's tenth smallest country in area and fourth most densely populated sovereign country. Its capital is Valletta, which is the smallest national capital in the European Union by area at 0.61 km2 (0.24 sq mi). The official and national language is Maltese, which is descended from Sicilian Arabic that developed during the Emirate of Sicily, while English serves as the second official language. Italian and Sicilian also previously served as official and cultural languages on the island for centuries, with Italian being an official language in Malta until 1934 and a majority of the current Maltese population being at least conversational in the Italian language.
