Michael Riddell Akua (born 26 January 1963[1]) is a political figure from the Pacific nation of the Republic of Nauru.

[3][4] He was elected again Speaker in Parliament during the first three months of Marcus Stephen's presidency, from December 2007 to March 2008.

He resigned on March 18, to prevent the Opposition, led by David Adeang and former President Rene Harris (who died of ill health several weeks later), from submitting a motion of no confidence against Stephen.

Akua was seen as a close ally of President Marcus Stephen, whose government ceased to command the support of a majority in the Parliament of Nauru in March 2008.

Akua's resignation was thus set in the context of strengthening the Executive by hindering the conduct of Parliamentary business, which, as widely acknowledged, would likely have led to the term of office of the Stephen Administration being ended by Parliament.
