Sudan's former ruling party; the National Congress Party (NCP) has been disbanded, BBC has reported.
The party was disbanded after the Sudanese government revoked the Public Order Law.
Protesters had demanded the dissolution of the ex-ruling party and the repeal of the draconian moral policing law.
The dissolution of the National Congress Party (NCP) now gives the transitional authorities power to sieze its assets.
A spokeswoman for the Sudanese Professionals Association hailed the dissolution of the former ruling party as a historic milestone.
"This is a moment of relief, because each and every person in Sudan has been affected in some way or the other by this regime in a negative manner," spokeswoman Samahir Mubarak told the BBC.
The transitional authority was established after a power-sharing agreement was struck between civilian protesters and military generals.
The announcement of the dissolution of the ex-ruling party was confirmed the country's prime minister.
"We have passed this law in a joint meeting with our partners in the Sovereign Council to take its full legitimacy," Sudan's Prime Minister Abdalla Hamdok said as quoted by Gulf Today.
