Martin A. B. K. Amidu is a Ghanaian politician. He was the Attorney-General and Minister for Justice from January 2011 till January 2012.

He is the man, who introduced the word ‘gargantuan’, into the lexicon of Ghanaian politics, when he opened the can of worms about the Woyome scandal which was set to be the worst financial scandal in Ghana’s fiscal history at the time.

Amidu served as the Deputy Attorney-General for about the last four years of the Provisional National Defence Council military government. Amidu is a member of the National Democratic Congress(NDC).

After civilian rule was established in the Fourth Republic in January 1993, he continued to serve in the government of Jerry Rawlings as Deputy Attorney-General. This he did for both terms lasting eight years until January 2001.

In the December 2000 presidential elections, he stood as the running mate of John Atta Mills. They however lost to President John Kufuor that year.

In January 2010, following a cabinet reshuffle, President Mills replaced Cletus Avoka with Amidu as the Minister for Interior. Following the second major cabinet reshuffle by President Mills, Amidu became the Attorney-General and Minister for Justice of Ghana.

Martin Amidu was relieved of his post on Thursday January 19, 2012 by President John Evans Atta Mills under circumstances described by aids as 'his misconduct' at a meeting chaired by the president at the Osu Castle on January 18, 2012. He made allegations related to alleged financial impropriety on the part of another cabinet minister, allegations he was asked by the president to substantiate.

Martin Amidu, the former Attorney General, single-handedly challenged the legality of the payment of GHS52 million to businesman Alfred Woyome, at the Supreme Court after being relieved off his post. The Supreme Court in 2014 ordered Mr. Woyome to pay back the money as Supreme Court judges unanimously granted the Attorney-General clearance to execute the court’s judgment, ordering Mr. Woyome to refund the cash to the state.

Following the delays in retrieving the money, Mr. Amidu in 2016, filed an application at the Supreme Court seeking to examine Alfred Woyome, on how he would pay back the money, after the Attorney General’s office under the Mahama Administration, led by the former Minister for Justice, Marietta Brew Appiah-Oppong, discontinued a similar application.

In February 2017 however, Mr. Amidu withdrew his suit seeking an oral examination, explaining that the change of government under the New Patriotic Party under His Excellency the President, Nana Addo Dankwah Akuffo Addo and his Attorney General, Miss Gloria Akuffo’s assurance to retrieve all judgment debts wrongfully paid to individuals.

Mr. Woyome in response prayed the Supreme Court to stay proceedings on the oral examination since he had filed for a review on the case.

His lawyer, Ken Anku, argued that, his client will face an irreparable damage if the oral examination is allowed to take place but the deputy Attorney General, Godfred Dame, opposed the application, describing the reasons as incompetent and unmeritorious.
