ANALYSIS With more than half a million Malaysians working in Singapore, the apparent political shift in the Singapore election campaign is set to shake Malaysia's political landscape, especially in the southern state of Johor - deemed to be Umno last bastion in the peninsula.

In this polls, described by many as the toughest battle faced by ruling party People's Action Party (PAP) since 1960s, the opposition campaign had gained impressive momentum, reflected by the attendance of animated crowds numbering in the tens of thousands at their mega-rallies over the past few days.

It has not only rung the PAP's alarm bell but also received wide coverage from both the international and Malaysian media.
