The former premier made these remarks while addressing a gathering in Mansehra on Sunday.
He said that the people of Pakistan have now lost hope in the incumbent government to lead the country towards the path of progress and development.
Abbasi remarked that the current government was not working for the betterment of the public and instead it halted all the projects which were launched by the PML-N government.
Regarding the accountability process, he said that the allegations levelled against Nawaz Sharif were baseless. He said that during his tenure as the prime minister neither he nor any minister was involved in corruption.
