Malaysian politics was degenerating to a level of being dirty with the opposition using slander and statutory declaration to achieve their political objectives, Datuk Seri Najib Tun Razak said today.

The Deputy Prime Minister said the opposition was inclined to make fools of the rule of law and politicise cases currently being tried in court to change people's perception towards government leaders.

"I mention this as a principle, meaning if we love our country we must realise that to build a country like Malaysia is not something easy. Don't we do something that can destroy what we have done.

"Secondly, the rule of law is very important. Don't we talk about law of the jungle and so on but we ourselves are not practising it," he told reporters here Saturday.

Najib said slander was not something new in politics but the information technology era has enabled slander to spread wider and quicker.
