ODM leaders have threatened to walk out of the broad-based government if the State fails to arrest and prosecute the killers of slain Kasipul MP Ong'ondo Were.
Were was killed by an unknown gunman who shot him severally on Nairobi city's Ngong road on Wednesday evening.
His death has elicited tension in Kasipul Constituency, Homa Bay County.
But the death is now threatening the sustainability of the broad-based government signed by President William Ruto and ODM Leader Raila Odinga.
