Zimbabwean opposition leader Morgan Tsvangirai is due in Belfast tomorrow.
He and Senegalese President Abdoulaye are set to address the 55th Congress of Liberal International (LI) tomorrow morning.
Mr Tsvangirai, who claims his Movement for Democratic Change won the recent presidential elections, will address worldwide liberal party members.
Mr Tsvangirai beat President Robert Mugabe in the first round on March 29th - but with not enough votes to avoid a run-off. Zimbabwe's electoral commission said on Wednesday the presidential run-off could be delayed until the end of July.
Official results showed that opposition leader Morgan Tsvangirai beat President Robert Mugabe in the election but not by enough votes to avoid a run-off.
Conference organiser Lord Alderdice said: “We are honoured that Mr Tsvangirai and President Wade have chosen to attend our Congress in Belfast. It is a city often seen as an example that conflict can be overcome when people choose peace and democracy over violence and tyranny."
LI is the world federation of liberal and progressive democratic political parties. It was founded in 1947 to strengthen liberal protection from totalitarianism, fascism and communism.
