Ayer Hitam MP Datuk Seri Dr Wee Ka Siong has urged Economics Affairs Minister Datuk Seri Mohamed Azmin Ali to furnish more evidence to back his claims that the Kuala Lumpur-Singapore high speed rail (HSR) project would cost taxpayers an estimated RM110bil. The MCA deputy president also expressed shock towards a recent statement made by Finance Minister Lim Guan Eng that the government could halve the cost of the project to RM55bil.
