Dr Mahathir Mohamad appears to have made it clear that he intends to demolish BN, the coalition which he led for two decades, said Tengku Adnan Tengku Mansor.

Previously, the BN secretary-general pointed out, Mahathir had trained his guns on Prime Minister Najib Abdul Razak alone.

However, Tengku Adnan noted, the former prime minister is now with the opposition, based on his recent remarks on the forthcoming Sungai Besar and Kuala Kangsar by-elections.

"He (Mahathir) said not to vote for BN in the by-elections...

"This is clear-cut that he is with the opposition party and wants to kill our party," Tengku Adnan, who is often referred to as Ku Nan, told reporters when met at the sideline in Parliament.

Two days ago, Mahathir urged the opposition to stand as one to defeat BN at the upcoming by-elections in Sg Besar, Selangor and Kuala Kangsar, Perak.

“This fasting month we will face two by-elections, and I hope we all can defeat BN this time.

“It doesn’t matter who leads the fight, we must have only one party to fight BN because we know if there are two or three (opposition) candidates like what had happened in Sarawak, the votes will be split and BN will win.

“If we have only one to one fights, we are sure to defeat BN by giving all our collective votes to the candidate contesting against BN.”
