The APNU was formed on 24 June 2011 as a
political alliance between major opposition party PNC and
three smaller parties: the Guyana Action Party (GAP), the
National Front Alliance (NFA) and the Working People’s
Alliance (WPA). The PNC, along with the PPP/C is one
of the two largest political parties in Guyana. The PNC
formed in 1957 after a split between leader Forbes Burnham
and Guyanese “founding father” Cheddi Jagan, who ruled
Guyana from independence in 1966 until 1992.

On 14 February 2015, the leaders of A Partnership for National Unity (APNU) and Alliance for Change (AFC) signed the “Cummingsburg Accord.” Through this Accord, both parties will contest the 2015 elections on a single list of candidates; with the APNU nominating the Presidential candidate and AFC nominating the Prime Ministerial candidate.

Prior to the 2015 elections, the APNU formed a joint electoral list with the Alliance for Change. The combined list won 33 seats, allowing PNC leader David A. Granger to become President.
