Charamba, who is now President Emmerson Mnangagwa's spokesperson, said that the new government was keen to show respect to Mugabe.
Harare-The Zanu PF Extra-Ordinary Congress on Friday unanimously endorsed the appointment of President Emmerson Mnangagwa as the President and First Secretary of the ruling party.
Finance Minister Patrick Chinamasa also started referring to Mugabe as the party's candidate for elections due in 2018 before correcting himself.
"We call for the unconditional lifting of the political and economic sanctions, which have crippled our national development", Mr Mnangagwa told party leaders in central Harare.
Mnangagwa also appointed Victor Matemadanda as secretary for War Veterans, Detainees and Restrictees, while Christopher Mutsvangwa was appointed Zanu-PF secretary for Science and Technology, taking over from Professor Jonathan Moyo, who was also expelled from the party.
The military stepped in on November 14 and ushered Mnangagwa into office after a power struggle with supporters of Grace Mugabe, 52, who had emerged as Mugabe's chosen successor.
The president also said that elections were "nearer than you expect".
Mnangagwa said he will appoint two vice Presidents in the next few days.
Charumbira took a swipe at the former First Lady Grace Mugabe for the fall of her husband Mugabe. Defence Forces Commander General Constantino Chiwenga is a strong contender for one of the vice presidency slots as a reward for spearheading the de facto coup that ended Mugabe's rule.
Mnangagwa, whose sacking as vice-president set off the chain of events that led to Mugabe's removal, said the ZANU-PF congress should define a new trajectory - which he did not spell out - and put behind it the victimisation of members seen in the past.
