ALOR SETAR: Datuk Seri Mukhriz Mahathir announced his resignation as the Kedah Mentri Besar on Wednesday.
At a packed press conference held at his office in Wisma Darul Aman, Mukhriz said the resignation will take effect immediately.
He said he made the decision to resign as he has lost the majority support of assemblymen in the state assembly.
Mukhriz said he has informed the Kedah Regency Council of his resignation on Tuesday.
"I feel a heavy burden lifted off my shoulders," he said.
Kedah Gerakan chief Cheah Soon Hai, Sungai Tiang assemblyman Datuk Suraya Yaacob and Jitra assemblyman Datuk Aminuddin Omar joined Mukhriz at the press conference.
Mukhriz said he had also rejected an offer to be a deputy minister offered by Prime Minister Datuk Seri Najib Tun Razak.
"I will continue to be vocal . Umno must undergo drastic transformation," he said.
Replying to a question on who he wished to be his replacement, Mukhriz said: "Ahmad Bashah."
Mukhriz said he has not informed his father Tun Dr Mahathir Mohamad of his decision to resign.
