Former Prime Minister Raila Odinga has renewed calls for constitutional reforms to elevate the Senate to the upper house of Parliament as originally envisaged under the 2010 Constitution.

Addressing Senators during a sensitisation meeting organised by the Senate Finance Committee on the fourth basis revenue-sharing formula, Raila urged both Houses of Parliament to adhere strictly to their constitutional mandates.

His call is likely to provoke resistance from MPs, particularly over his proposal to scrap bursary funds allocated to the lawmakers, insisting they should focus solely on their oversight role.

Raila made the rare address at the invitation of Senate Speaker Amason Kingi, in an informal sitting held in recognition of hiss role as the 'father of devolution'.
