Mr Seidu Seini, Northern Regional Secretary of the National Democratic Congress (NDC), has resigned, citing marginalisation and lack of co-operation from the regional party leadership.
In a letter addressed to the National Chairman of the Party and copied to the press, Mr Seini, who has been the Regional Secretary for the past six years, said he had been sidelined at the regional level and not been involved in major decisions.
"I hear some of their decisions on the air", he said.
He said the party leadership had treated him with contempt to the extent that he was not made member of the Northern Region Reorganisation Committee of the NDC.
Mr Seini, a retired educationist, said by such action "I am not considered useful to the party, but a stumbling block to the political ambition of others".
"I did not receive the necessary co-operation of the party leadership to deliver, however, I continued to exercise patience for a long time."
Mr Seini said he was resigning in dignity to pave the way for the NDC to choose another person, who was in the good books of the party leadership.
