Kawempe North MP Muhammad Ssegirinya has been flown to Nairobi in Kenya for further treatment.
Mr Updates was rushed to hospital over the weekend after he collapsed at home.
He reportedly had severe dysentery after his release from Kitalya prison.
A video recorded on Monday April 18, 2021 shows Ssegirinya being wheeled in a patient chair at Entebbe Airport.
This was shortly after he was referred to Agha Khan hospital in Nairobi.
The referral follows ear and abdominal complications.
