The next few years under the Momoh administration were characterised by corruption, which Momoh defused by sacking several senior cabinet ministers. To formalise his war against corruption, President Momoh announced a "Code of Conduct for Political Leaders and Public Servants". After an alleged attempt to overthrow President Momoh in March 1987, more than 60 senior government officials were arrested, including Vice-President Francis Minah, who was removed from office, convicted of plotting the coup, and executed by hanging in 1989, along with five others.
