President Pratibha Patil on Friday signed the proclamation to revoke Central rule in Karnataka.
Patil, who is at present on a visit to Shimla, signed the proclamation and sent it to Union Home Ministry for issuing of requisite orders.
The signing of the proclamation comes ahead of the swearing-in of BJP's BS Yeddyruppa as Chief Minister of the state.
Central rule, which had expired on May 19, was extended by another six months after a meeting of the Union Cabinet chaired by Prime Minister Manmohan Singh took a decision in this regard.
The elections in the state were held in three phases on May 10, 16 and 22 which saw emergence of BJP as the single largest party.
