PKR vice-president Rafizi Ramli said he did not compare Malaysia's MRT project with Singapore's due to how problematic the latter's project was.

"I didn't pick Singapore's MRT because their cost overran twice, and the project was problematic," Rafizi said at a press conference in Kuala Lumpur today.

He also said that his critics would cite the high costs of Singapore land should he make comparisons between the two MRT projects.
