A caucus of parliamentarians on Human Rights wants Interior Secretary Joseph ole Lenku to expel from Kenya Sudanese leaders recently released from prison by President Salva Kiir.
Six members of the Caucus said the 11 leaders, currently living at Windsor Hotel, are supposed to help in the attainment of peace in the troubled country and not "live in opulence".
"They cannot live in opulence at the expense of Kenyan taxpayers and engage in selfish political reorganisation that does not help the course of South Sudanese people," said Wajir South MP Diriye Abdullahi.
"They should go to Ethiopia where the peace process is ongoing." Diriye was with MPs Ken Okoth (Kibra), Stephen Mule (Matungulu) and Neto Agostino (Ndhiwa) and Senator Daisy Kanainza.
The South Sudan leaders were released in February after being detained on allegations of plotting a coup against Kiir's government. Kiir surrendered the detainees to President Uhuru and they have been living in Kenya ever since.
