He ran as John Atta Mills' running mate in the December 2000 presidential elections. That year, they were both defeated by President John Kufuor

Following a cabinet reorganization in January 2010, President Mills appointed Amidu to replace Cletus Avoka as the interior minister. Some individuals questioned Amidu's impartiality in resolving the Bawku conflict because he is a Builsa. But he passed the Ghanaian Parliament's scrutiny and was given the position.

He served as Ghana's first special prosecutor from 2018 until his departure in 2020, after serving as the country's attorney general from 2011 to 2012.

President John Evans Atta Mills removed Martin Amidu of his position on Thursday, January 19, 2012, for what officials have referred to as "his misconduct" at a meeting he presided over at the Osu Castle on January 18, 2012.

He was Ghana's first Special Prosecutor to be proposed to the legislature. On January 11, 2018, Nana Akufo-Addo, the president of Ghana, announced the nomination.On Friday, February 23, 2018, President Nana Addo Dankwa Akufo-Addo administered the oath of office to Martin A.B.K. Amidu at the Flagstaff House. At the swearing-in ceremony, Amidu thanked the President and the Attorney General for choosing him and vowed to battle corruption in the nation without fear or favor.

Martin A. B. K. Amidu announced his retirement as a special prosecutor on November 16, 2020, blaming President Nana Akufo-Addo for political interference. Amidu argued that Akufo-Addo's response and interference in an inquiry were mistaken and that he was motivated by a lack of respect for his office's independence.
