After more than a week, the Conservatives say they're not sure how long it will take to translate secret recordings made by one of their members of Parliament, who is accusing top Liberals of trying to buy his vote.

Gurmant Grewal says the government tried to buy his support just before a confidence motion in the House of Commons on May 18.

At the time, he released eight minutes of tape from a conversation he recorded between himself and Tim Murphy, the prime minister's chief of staff.

Grewal alleges he was offered a diplomatic posting and his wife, who is also an MP, was offered a Senate seat if they sat out a vote on the government's budget.

The Liberals flatly denies the accusations.

But Grewal claims he has hours more tape of conversations he had with Health Minister Ujjal Dosanjh, but it is in Punjabi.

Grewal says he doesn't know when it will be translated.

"I don't know the time frame," he said. "As soon as they are ready, you will see them."

The Conservatives have been saying for the past seven days that they're working on a translation. Conservative House leader Jay Hill would only say that he hopes it will be ready soon. "I haven't seen them. I haven't heard them and I don't know Punjabi. So, I don't know how long it's going to take to translate them."

Conservative Leader Stephen Harper was saying nothing about Grewal's tape, even though the Conservatives are under increasing pressure to release them.

The Bloc Québecois and the NDP have called for an RCMP investigation.

The Conservatives say that when the translation is complete they will turn the tapes over to the police.
