Kuala Lumpur - Malaysia's former prime minister Mahathir Mohamad rejoined the ruling party Saturday, one year after he quit following a falling out with his successor.
Mahathir's decision to rejoin the United Malays National Organisation (UMNO) came a day after Najib Razak was sworn in as new prime minister.
Najib took over from Abdullah Ahmad Badawi, who had been Mahathir's chosen successor after he retired in October 2003.
