The move is seen as a significant step towards securing a free run for President Yoweri Museveni to seek re-election in 2021.
In 2005, an amendment was passed to remove term limits at a time President Museveni’s tenure had ended after two elective terms.
In 2006, President Museveni returned now as candidate for the National Resistance Movement, which had registered as a political party after the lifting of the ban on parties.
Members of Uganda's ruling National Resistance Movement Tuesday voted unanimously in favour of a motion seeking to amend the Constitution to remove the presidential age limit.
The move is seen as a significant step towards securing a free run for President Yoweri Museveni to seek re-election in 2021.
President Museveni, 72, is barred by the current Constitutional from vying again as he will have surpassed the 75-year mark by the next election.
The lawmakers' move is a significant step for a thinly-veiled process that has been playing out in the open without official endorsement.
President Museveni, the main beneficiary if the amendment is successful, dismissed the talk about two months ago saying he was concentrating on his programmes and age limit was not an urgent matter.
Yet members of his party and State House staff have been engaged in low-key, but intense mobilisation for the amendment.
Resolutions from Kisoro, a remote district at Uganda’s border with Rwanda and the DR Congo, Mbarara, the main city of the Ankole sub-region and a demonstration in Arua District, the headquarters of the West Nile sub-region supporting the lifting of the age limit, passed peacefully with police protection in a country where political gatherings, mainly for opposition activists, have often been violently broken by the security agencies.
An initial effort to present the change in a private members Bill by Nakifuma County MP Robert Kafeero earlier this year, was dismissed by some as a joke but was sufficient to set in motion a debate that has pervaded the country now for months.
Speaker of Parliament Rebecca Kadaga poured cold water on Mr Kafeero's effort when she ruled in July that the debate was unmerited at the time.
A special aide to the president, Mr David Mafabi, has been the public face of mobilisation for the age limit lifting, presiding over seminars in various parts of the country to popularise the move.
If successful, this will be the second major change to Uganda’s 20-year-old Constitution to directly favour President Museveni’s continued stay in power.
In 2005, an amendment was passed to remove term limits at a time President Museveni’s tenure had ended after two elective terms.
Mr Museveni first shot his way to power in 1986 after a five-year guerrilla war, and ran the country unelected for 10 years before presenting himself as a civilian in the 1996 elections under the individual merit Movement System.
In 2006, President Museveni returned now as candidate for the National Resistance Movement, which had registered as a political party after the lifting of the ban on parties.
Apart from 1996, all previous elections that President Museveni has won with comfortable margins, have been disputed as rigged and fraught with other malpractices.
The Supreme Court has upheld three of those elections, ruling that the existence of irregularities did not affect, in a substantial manner, the final outcome which the it said largely reflected the will of the people.
