Two ex-leaders of a Yorkshire tourism body held games over who could get the priciest wine on expenses, parliament heard.
Paul Scriven told the House of Lords that Welcome to Yorkshire (WtY) had a "culture of toxicity" and misused public funds .
An independent inquiry found expenses at WtY had been made without receipts.
Responding to the wine claims, the tourism body's former chair Ron McMillan said: "On no occasion that I recall has that been the case."
Speaking during a debate about extending the Freedom of Information Act, former Sheffield City Council leader Lord Scriven said he had attempted to investigate "major excesses" and "recent scandals" at WtY.
The debate was told WtY was made a private company in 2009 by Sir Gary Verity and had received over £10m in public money in the last decade.
"Excesses include luxury spending on helicopters, hotels at £600 a night [and] lavish meals during which the chief executive Gary Verity and the former chair Ron McMillan were playing games about who could get the most expensive wine on expenses," Lord Scriven said.
The BBC has approached WtY and representatives for Sir Gary for comment.
