But UPND deputy spokesperson Cornelius Mweetwa says the letter which Kabimba has is a forgery.
Kabimba told journalists earlier that the UPND fundamental proposals which were received through the UPND Chairperson for international relations Professor Clive Chirwa also included the proposal that UPND leader Hakainde Hichilema should be the vice president in government.
Kabimba added that the proposals also included the sharing of cabinet portfolios with the PF taking 60% and UPND 40% among other proposals.
He also said that the PF has also welcomed the UPND’s proposal that the two political parties design and agree on a common social and economic development agenda that a pact government will focus.
Kabimba said contrary to media reports that the pact had diminished, the two opposition political parties are still working together.
He said that the UPND-PF pact is a viable alternative government to the MMD during this year’s elections.
The UPND has launched campaigns for its leader Hichilema to stand for presidency this year. They call their campaign the ‘Real Change’ which in essence means new and young leadership in the next government.
