Senegalese President Macky Sall has scheduled a delayed presidential election for March 24, the government said on Wednesday after a top court ruled that a proposal to hold the vote after his mandate expires on April 2 was unconstitutional.

The announcement caps a dramatic evening that saw Sall dissolve the government and replace Prime Minister Amadou Ba with Interior Minister Sidiki Kaba so that Ba, the ruling coalition's presidential candidate, can focus on his electoral campaign, the presidency said.
