A furious Duale countered: "I challenge the deputy Speaker to contest against me either in Dujis or Balambala and I will defeat him."
Mwingi South MP David Musila engaged in a nasty exchange with his Mutito counterpart Kiema Kilonzo over Mwingi County politics.
Plans by Mr Kiema to run for Governor and Mr Musila the Senate seat stoked their differences. The Mutito MP unsuccessfully lobbied for a new constituency named Mwingi Central.
Musila countered: "No constituency was dropped. Mwingi South was split into two and renamed Mwingi West and East. What Kiema is doing is to incite people against elected leaders like myself and Vice-President Kalonzo Musyoka.
"If a member goes to another memberâs constituency, hires buses to ferry people to the National Assembly and pays them each Sh150 as they go home, that is bad manners," Musila charged, rallying members to oppose the proposal.
"I support Musila. Members should respect each otherâs territory," said Gem MP Jakoyo Midiwo.
Immigration Minister Otieno Kajwangâ and Gwassi MP John Mbadi hit out at nominated MP Millie Odhiambo over an attempt to shift some parts of Gwassi constituency to Mbita constituency.
"This committee changed boundaries in Suba without consulting two elected MPs in the area because there is a nominated member who sits there," Mbadi claimed. "She moved the changes working with some people who had scribbled some things on foolscaps that I intend to overturn."
Mbadi successfully lobbied for the reinstatement of Ruma Nyaboto and Nyadendi (Ruma Kaksingiri) to Lambwe in Suba North saying: "The area has Ruma National Park and it is also my support base."
Assistant ministers Asman Kamama and William Cheptumo clashed over a ward whose creation the latter claimed was ill-conceived given the area was a hot spot for clashes.
