A female senator has been removed from Chambers over inappropriate dressing.
Karen Nyamu from Kenya had on Tuesday tried to access the chambers in a sleeveless top, exposing her arms which is against the House rules, but was called out for her dressing.
The matter was petitioned by Migori Senator Eddy Oketch.
"I invite your attention to guide the House whether Senator Karen Nyamu is properly dressed," Oketch called the Speaker's attention.
He urged the Majority side to respect the rules of the House and Kenyans at large.
Speaker Amason Kingi ruled that the House rules had been violated, and ordered Nyamu to leave the chambers.
"Senator Nyamu, I'm going to read the Speaker's Rule No for clarity. Senators are required not to enter the chamber, lounge or dining room without being properly dressed," he said.
"This means a male Senator will be dressed in a coat, collar, tie, long trousers, socks and shoes or service uniform, religious attire or such other decent dressing as may be approved by the speaker from time to time. An equivalent standard shall apply in respect of women senators who may also wear kitenges or such other African attire."
In reference to the rule, Kingi added, "Senator Nyamu, I'm afraid you do not fit the bill and I'm going to ask you to leave the chambers, get properly dressed and come back to the chambers."
