KUALA LUMPUR: Umno's support for the Perikatan Nasional (PN) government has limits, says former premier Datuk Seri Najib Tun Razak.

His post on Facebook came amid cries from party members that Umno was under-represented in the current Cabinet line-up.

"Many don't understand that PN is not a Muafakat Nasional or Barisan National government.

"Therefore, our support for the PN government has limits," he said in his post, adding that this was why the Umno president, deputy president and Umno Youth chief were not part of today's cabinet.

He said they would defend the PN government until the 15th General Election.
