Sri Lankan MPs are to vote on proposals to let President Mahinda Rajapaksa seek an unlimited number of terms, in a move critics say could lead to dictatorship.
As well as abolishing the current two-term limit, the constitutional amendments would hugely increase the president's powers.
On Tuesday, the Supreme Court cleared a draft bill, ruling MPs could vote the changes in by a two-thirds majority.
The government is expected easily to secure the margin required.
On Wednesday, Prime Minister Dissanayake Mudiyanselage Jayaratne presented the amendment to parliament and said there was nothing undemocratic in the plans.
