AICC secretary and MLA Asha Kumari has been included in the state election committee as a member.
Congress vice president Rahul Gandhi last week named Mr Singh as a member of the campaign committee of which Mr Sukhu was the chairman and Rajya Sabha member Viplove Thakur a co-convener.
AICC general secretary Janardan Dwivedi said in a statement today said Mr Gandhi had approved the name of Virbhadra Singh as the committee chairman for the assembly elections in the state. "The campaign committee was announced earlier," he said.
Mr Singh and Mr Sukhu have been at loggerheads with the former demanding his immediate replacement as the PCC chief ahead of the elections, scheduled for November 9.
They have also shared other public platforms of late. Asked about the differences within the party, Mr Singh said the Congress party in Himachal Pradesh was united and would fight the election together.
The chief minister also launched the party's campaign for the state - "Jawaab dega Himachal" (Himachal will give its reply) -- on the development initiated in the state under his leadership, as a counter to the BJP's campaign targeting him for corruption.
