A BN strategic communications team has again rubbished PKR vice-president Rafizi Ramli's claims of escalating costs of the Mass Rapid Transit (MRT) project.

In a statement last night, the anonymous group zoomed in on Rafizi's Tuesday claim that the 51km MRT1 project from Sungai Buloh to Semantan was completed at double the price of similar projects in Spain and South Korea.

"It is clear that both the MRT Seoul and Barcelona projects cited by Rafizi were more expensive than the MRT1 project in terms of costs per kilometre," said the group, citing official data by relevant authorities from South Korea and Spain.
