Dr Mahathir Mohamad is prepared to end his working relationship with PKR if it continues to oppose his candidature for the prime minister post.

In an exclusive interview with Sin Chew Daily, the nonagenarian said he would stop collaborating with PKR president Anwar Ibrahim if the impasse is not resolved and explore other means to become prime minister for the third time.

However, Mahathir said he would continue to work with DAP and Amanah since the two parties supported him for the top post.
