Malacca Chief Minister Idris Haron has come under fire for saying that turning the state into a federal territory was a possibility in future.

Malacca opposition leader Khoo Poay Tiong said the state had over 600 years of history, long before Tanah Melayu or the Federation of Malaysia was formed.

"How could he make such a statement that Malacca becoming a federal territory is a possibility?

"Malacca state as we know it would disappear along with its long history. It is unacceptable," said the DAP assemblyperson in a statement today.
