BNP secretary general Mirza Fakhrul Islam Alamgir on Thursday alleged that the ruling government is conspiring to split their party.
He said, "Many plots are now going on to weaken BNP and split it. They (govt) also tried to do so in the past, but failed."
He came up with the allegation while speaking at a milad mahfil at the party's Nayapaltan central office.
Fakhrul further said, "We would like to unequivocally say they won't be able to divide BNP as it revived like phoenix bird repeatedly whenever it faced devastation in the past."
BNP arranged the programme marking the fourth death anniversary of party chairperson Khaleda Zia's younger son Arafat Rahman Koko.
Fakhrul urged his party colleagues to go to people to mobilize support in favour of their party and its politics to strengthen BNP further.
He also urged the democratic and patriotic forces to get united to defeat the current government as it has taken a position against people and democracy.
The BNP leader recalled the contributions of Koko to the country's sports sector and prayed for salvation of his departed soul.
He called upon BNP leaders and activists to get organised to have their chairperson Khaleda Zia freed from jail.
Earlier in the morning, BNP leaders and activists, led by Fakhrul, offered fateha at Koko's grave at Banani Graveyard in the capital.
On January 24, 2015, Koko died of cardiac arrest at the age of 45 at his rented house in Malaysia. His body was brought back home on January 27 and buried at the Banani Graveyard.
