"This government has destroyed more jobs than it has created. The only job they can point to is NABCo, and yet they have destroyed more than 10,000 jobs in the bank sector," he said.

Mahama cited Groupe Ndoum's GN Bank as an example of an institution purportedly failed by the state.

"All the GN banks used to have staff in them all over the country. Today where are those staff? They are all sitting at home," he noted.
