"If this attempt is failed, they will try to foil the election by creating unwanted situation in the country. Any invisible force's involvement in this conspiracy is not unlikely," he said while addressing the inaugural session of the 8th Rokon (member) conference of the party at Paltan Maidan in the city.

Senior Joint Secretary General of Bangladesh Nationalist Party (BNP) Tarique Rahman and Health and Family Welfare Minister Khandaker Mosharraf Hossain also addressed the meeting.

Nizami said the AL and its allies are trying to make the caretaker government system controversial in an "illegal and irrational" way.

"Parliamentary elections under this system have been appreciated at home and abroad. Two elections were held under this system. So, creating controversy over the next election under the system is totally irrational," he told his audience.

Pointing out the recent upheaval in the garment industry, the industries minister said being envious of present government's success in the apparel sector, a vested quarter is provoking such arson attacks on the garment units in a planned way to destroy the industry.

He urged the leaders, workers and supporters of the four-party coalition to give the highest importance to the upcoming elections as he said there is no alternative to national unity to foil the conspiracy being cooked up in and outside the country against Bangladesh.

Tarique Rahman in his welcome address said the four-party alliance has to move forward casting aside all the differences of opinion in greater interest of the alliance.

Terming the four-party alliance a family, the BNP leader said, "Having different opinions among the members of a family is nothing unusual. But we have to move ahead leaving behind the differences for the unity and greater interest of the family."

"We moved forward leaving all our differences behind in the past and we will do the same in the future to make our unity far stronger," he told the Islamist party cadres.

Former ameer of Jamaat-e-Islami Bangladesh Golam Azam, Secretary General and also Social Welfare Minister Ali Ahsan Mohammad Mujahid, Nayeb-e-Ameer Delwar Hossain Saidee MP and Abdus Sobhan MP were, among others, present.
