Togo's main opposition leader has said his party will only participate in legislative elections announced by the country's new president if African leaders guarantee their fairness.
Mr Gilchrist Olympio said he had no confidence in Mr Faure Gnassingbe, who was contoversially sworn in as President on Monday.
Mr Olympio, who leads the Union of Forces for Change, also said he had no confidence in the army which supported Mr Gnassingbe succeeding his father as President.
And he criticised the absence of any declaration on when presidential elections would be held in the West African state.
"When the conditions are right our party will participate in the elections, but they are not right," Mr Olympio said from Paris where he has been in exile since a 1992 attempt on his life.
Togo's army installed Mr Gnassingbe president on Saturday following the death of his father earlier that day. Mr Gnassingbe Eyadema, Africa's longest serving leader, died after 38 years in power.
The National Assembly changed the constitution to sanction the succession retroactively. African leaders have called it a military coup and the African Union has threatened Togo with sanctions.
In a national address today Mr Gnassingbe promised reform and said he wanted "free and transparent" legislative elections as soon as possible.
Responding to the speech, Mr Olympio said: "We are saying that an agreement signed with the Eyadema government, father or son, has no value."
"Now if you have guarantees from ECOWAS [the Economic Community of West African States] ... the African Union and perhaps the European Union, it will have value because you will have someone who will tell you these things will be respected."
Meanwhile, African leaders are holding an emergency summit in Niger today to discuss the succession.
African heads of state, former colonial power France, the European Union and the United Nations have all urged Togo to respect the constitution and let the Togoan people choose a new leader in an election.
The European Union suspended aid to Togo in 1993 because of "democratic deficiencies".
