President Joyce Banda has said she wants Malawi to overturn its ban on homosexual acts - the first African country to do so since 1994.
Two Malawian men were sentenced to 14 years in prison in 2010 after saying they were getting married.
Several Western leaders have recently said they would cut aid to countries which did not recognise gay rights.
Mrs Banda took power last month after her predecessor, Bingu wa Mutharika, died of a heart attack.
She has since reversed several of his policies, including devaluing the currency, in a bid to get donor funding restored.
The BBC's Raphael Tenthani in the main city, Blantyre, says the president has the support of a majority of MPs and so should be able to get parliament to overturn the law.
