An opposition newspaper that published a cartoon of Prime Minister Dr Mahathir Mohamad with a pig's snout should have its permit reviewed, said outraged lawmakers.

The cartoon in the Harakah newspaper of the hardline opposition Islamic Party PAS was "most irresponsible and downright rude", the chairman of the government's Backbenchers Club, Mohd Zin Mohamad, was quoted as saying by the official Bernama news agency.
