Mozambique's parliament has created a committee to draft amendments to the constitution that analysts have warned could be used to allow President Armando Guebuza to stand for a third five-year term.
The creation of the committee comes a year after ruling party Frelimo won enough seats to change the charter unilaterally.
Frelimo, the party that has ruled Mozambique since independence from Portugal in 1975, voted to create the ad-hoc commission over unanimous dissent from opposition parties, state news agency AIM reported.
"It's not the right moment to reform fundamental law since there are other priorities like food production and building schools and hospitals," Saimon Macuiana, a member of opposition party Renamo, told state daily Noticias.
Despite concerns that Frelimo could use its parliamentary super-majority to allow President Guebuza to stand again, both the president and the party have said they have no such plans.
Guebuza won 75 percent of the vote to cruise to a landslide re-election in October 2009.
Frelimo took 191 of the 250 seats in Mozambique's parliament, putting it for the first time above the two-thirds majority required to change the 1990 constitution.© ANP/AFP
