DAP and PAS have urged the Anti-Corruption Agency (ACA) to conduct immediate investigation into the multi-million ringgit logging scandal in Umno Pahang which reeks of high-level corruption.

DAP national publicity chief Ronnie Liu said "the ACA should have enough grounds to start investigation immediately" from the series of reports published in malaysiakini earlier this week.

"The silence from top Umno leaders on the logging scandal is deafening," he said in a statement yesterday.

"We hope ACA will not deliberately avoid probing this case just because it involves the most powerful ruling party in the country."
