Barisan Nasional will lodge complaints to the Election Commission (EC) following allegations of the existence of "phantom voters" during the Sungai Limau by-election, said Minister in the Prime Minister's Department Datuk Seri Shahidan Kassim.
He said the main problem was caused by the voters themselves who had not updated their addresses on their MyKad.
"We faced huge problems during the Sungai Limau by-election as we could not detect the listed voters. We will lodge official complaints to the EC in all constituencies to ensure the issue of phantom voters will be resolved.
"We have highlighted this to the EC before, but they told us that they could not do anything about it as the voters did not change their addresses," he said at the Parliament lobby.
The last electoral redelineation exercise was completed in March 2003 and while the next review should have started in March 2011, the EC had decided to postpone it due to preparations for the 13th general election.
Shahidan, who is also an Umno supreme council member, said he would bring the matter up to the Parliamentary Select Committee on Electoral Reforms.
He also called on the EC to review the security measures and procedures in regard to space provided for political supporters during a by-election.
"If different supporters are standing too close to one another during polling, fights will tend to occur," Shahidan said.
