KUALA LUMPUR: The Attorney-General's Chambers (A-GC) must explain why it delayed the implementation of Datuk Seri Najib Razak's house arrest order last week.

Barisan Nasional (BN) MPs secretariat chairman Manndzri Nasib also questioned the reason for the postponement, which was reportedly due to ambiguity and legal implications.

"What was the real obstacle, and has the rectification of the documents resolved it?

"If the solution was to issue a new warrant or correct the documents, the A-GC must explain why this was not coordinated earlier or pursued immediately after the problem was identified," he told a press conference at Parliament today.
