While some PAS leaders are complaining about foreign intervention in the 1MDB affair, the party's deputy president Tuan Ibrahim Tuan Man has acknowledged that the US Department of Justice's investigations on funds related to the firm was a result of Malaysia's failure.

"In the 1MDB issue, the failure of our enforcement institutions to transparently investigate the 1MDB scandal has made room for others who were more willing to investigate," he said in a statement today.

This includes failure to declassify the auditor-general report on 1MDB and the Malaysian Anti-Corruption Commission's (MACC) unwillingness to probe the matter, he said.
