Putrajaya's habit of taking large loans to fund projects, coupled with the continued depreciation of the ringgit, would bankrupt the country, warned Dr Mahathir Mohamad.

In a post on his blog today, the former prime minister said Malaysians must protest against such borrowings because of the financial burden it posed to the country in the future.

He said the East Coast Rail Link (ECRL) and the proposed high-speed rail from Kuala Lumpur to Singapore alone would mean Putrajaya had to take RM100 billion in loans.
