Former deputy prime minister Anwar Ibrahim was conspiring to topple then prime minister Dr Mahathir Mohammad even as he publicly pledged support for him, the Kuala Lumpur High Court was told today.

The witness Lokman Noor Adam testified that Anwar had voiced support for Mahathir at the 1998 Umno general assembly, and he was there to hear Anwar's speech. Mahathir was the Umno president at the time, with Anwar as his deputy.
