Kuala Lumpur- Malaysian opposition leader Anwar Ibrahim on Wednesday insisted that sodomy allegations against him have not changed his plans to take over the country's government on September 16.

Anwar's rising political star appeared to have hit a glitch last month when a former male aide accused him of sodomy.

Anwar rejected the accusations as a plot to end his political career, and claimed that talks and plans by the three-party opposition alliance to replace the government were still underway.

"We're still on track, but it's not an issue of toppling the government. It's ensuring that the people are the ones who win," Anwar said at a press conference.

Anwar, the chief opposition leader and self-proclaimed "prime minister-in-waiting," insisted that the sodomy allegations would not deter efforts to take over in September.

"No, no we're not changing the deadline," he said. "We are all tired of this political turmoil, sluggish economy, intimidation of the police and corrupt judiciary."

Last week, Anwar was detained for questioning on the sodomy allegations, and then released a day after on police bail.

Upon being released, the former deputy prime minister declined to comment on his take-over plans, fuelling rumours that his political ambitions had been hard hit by the fresh accusations.

Anwar was fired by former prime minister Mahathir Mohamad in 1998 and charged with sodomy and using his position to cover up the crime.

Anwar was found guilty on both charges and jailed for six years before he was eventually cleared of the sodomy charge.

The charismatic leader said Wednesday that he would "put up a major fight" against the latest allegations against him.

"I have very real reasons to believe there will be tampering of evidence, just like in 1998," he said. "We will put up a major fight against it this time."

After leading the opposition to major gains in the March 8 elections, Anwar announced it was ready to take over the government after several sitting legislators indicated their willingness to change their affiliation to his party.

The opposition managed to wrest control of five states and deny the ruling government of a two-thirds majority in parliament for the first time in history. (dpa)
