Dozens of Kenyan MPs face arrest
Mr Murungi is a close ally of President Mwai Kibaki A total of 65 MPs are among thousands of Kenyan officials who could be arrested from as early as next week. Under Kenya's anti-corruption law, all public officials are required to declare their assets each year.
Speaking on Kenyan television, Justice Minister Kiraitu Murungi said he had ordered that those who had not filed their forms be charged in court.
The forms are confidential and only accessible to anti-corruption police during investigations.
"These are very simple cases because the question is simple," he said
"In 2003 did you declare [your wealth]? If the answer is no, I don't see us spending two weeks in court arguing about such a case," he said.
In 2003, President Mwai Kibaki, who was elected on an anti-corruption platform, warned that those who do not make declare their assets could lose their jobs, and be liable to imprisonment.
Donors have been growing increasingly critical of the Kenyan government's record on tackling corruption.
