Former Speaker of the House of Representatives, Michael Peart, is not yet ready to apologise for his allegations that a report on the Cuban light-bulb project was leaked to the media by someone in the Office of the Contractor General.

Peart made the allegation in Parliament and later went on radio to claim that he had evidence to support his charge.

But Contractor General Greg Christie said there was no truth to the claim and he was demanding a public apology from the People's National Party member of parliament.

In a letter to the speaker of the House, dated February 25, Christie said a full investigation has revealed nothing to support the allegations.

According to Christie, an email produced by Peart did not originate in the Office of the Contractor General and there was a clear indication that the copy of the report supplied to the media came from one of 11 originals sent to state agencies.

"Mr Peart has made a very serious and damaging allegation which he has not only failed to substantiate, but which is incapable of any credible substantiation," Christie added.

"I must, therefore, prevail upon you, Honourable Speaker and the Honourable House, to formally call upon Peart to retract his statement and to issue an unconditional public apology for the irresponsible, reckless and defamatory allegation which he has made."

However, in his response, Peart said he was not yet convinced that the report had not been leaked from the Office of the Contractor General.

According to Peart, he has written to the speaker of the House seeking additional information.
