Bersatu is mulling legal action against the Prime Minister's Office and Cambridge Analytica, as well as its parent company SCL Group, and its Southeast Asia head Azrin Zizal.

Bersatu strategic director Rais Hussin said this is over the "fake news" allegations that the party’s deputy president Mukhriz Mahathir had engaged CA and SCL Group to help BN's 2013 election campaign in Kedah.

"We are tracking this fake news diligently, and we will not hesitate to take legal action against the perpetrators of such fake news, upon due consultation with our legal team," Rais told Malaysiakini.
