2010 Tongan Legislative Assembly

The 2010 Tongan Legislative Assembly was established following the 2010 elections, the first under a new system which saw the majority of seats elected by universal suffrage. The Taimi Media Network described it as "Tonga's first democratically elected Parliament".

The Speaker of the 2010 Assembly was Lord Lasike, until he lost his seat in Parliament on 18 July 2012, following conviction for illicit ammunitions ownership. He was replaced as Speaker by Lord Fakafanua. The Deputy Speaker was initially Lord Tuʻiʻafitu, until he was appointed Minister for Health on 2 July 2012, whereupon he was replaced by Lord Tu'iha'teiho.
