"Jatiya Party is a party of possibilities; party for change. We have huge prospects ahead of us," he told a rally in Rangpur on Saturday.
A mass uprising, led by the Awami League and BNP, forced the former military dictator to demit office in the early 1990s.
Prime minister's Special Envoy Ershad feels the Sheikh Hasina government failed to run the country. The Jatiya Party, which sits in the opposition, is also part of the Awami League-led government.

"They don't have the capacity to start an agitation with the people. Threatening to launch an agitation is the only thing they can do now," the Jatiya Party chief said.
