Sudanese Prime Minister Abdalla Hamdok said on Sunday he was resigning, six weeks after being reinstated as part of a political agreement with the military.

Hamdok, who had failed to name a government as protests continued against a military takeover in October, said a roundtable discussion was needed to produce a new agreement for Sudan's political transition to democracy.

"I decided to give back the responsibility and announce my resignation as prime minister, and give a chance to another man or woman of this noble country to ... help it pass through what's left of the transitional period to a civilian democratic country," Hamdok said in a televised address.

The announcement throws Sudan's political future even deeper into uncertainty, three years after an uprising that led to the overthrow of long-time leader Omar al-Bashir.

An economist and former United Nations official, Hamdok became prime minister under a power-sharing agreement between the military and civilians following Bashir's overthrow.
