Fifteen of the 20 candidates approved to stand in Senegal's delayed presidential elections have called for the new vote to be held no later than 2 April - the date when current President Macky Sall is due to end his term.
The 15 candidates also insist the list should not be altered.
The document was signed by some of the leading contenders, including Bassirou Diomaye Faye, who has been detained on incitement charges, and former Dakar mayor Khalifa Sall, who is no relation to the president.
President Sall wanted to postpone the elections for several months so that disputes over the eligibility of other candidates could be resolved.
But the country's top court said the delay was unconstitutional and Mr Sall says the vote will now be held "as soon as possible".
