Senior lawyer Ambiga Sreenevasan today says the government has been blacklisting law firms that support Bersih for some time now.

This was only made official by Minister of the Prime Minister's Department Abdul Rahman Dahlan who had instructed government-linked-companies to do so, she said.

"The threats to blacklist companies and firms come as no surprise. It is nothing new.

"They are merely making public what we believe their practice has been for some time," she said in a statement today.
