JOHOR BARU: One day after advising Datuk Seri Abdullah Ahmad Badawi to "shut up" after stepping down as prime minister, Tun Dr Mahathir Mohamad continued to criticise his successor.

Dr Mahathir scoffed at Abdullah's pledge to complete institutional reforms before leaving office.

"He only has a few months (to complete the reforms)," he told reporters after a Hari Raya function hosted by a Johor Umno grassroots action body yesterday.

Earlier in his speech, Dr Mahathir blamed Abdullah for "destroying" Umno following the party's dismal performance in the last general election.
