MORE than £4,700 of tax-payers money was spent by the Welsh Government to put up a millionaire property dealer at Cardiff's Hilton Hotel.
David Godstone, the only man to chair both Swansea and Cardiff City football clubs, was accommodated at the four-star city centre hotel between June 2011 and June 2015, with the bill footed by the Welsh Government.
The £4,717 figure was revealed by a Freedom of Information Act.
Mr Goldstone is a Swansea-born commercial lawyer turned developer, Labour Party member and donor who acted as an advisor to former Business Minister Edwina Hart.
A spokesman for the Welsh Government said it paid the bills as Mr Goldstone, who lives in London's wealthy Mayfair area, had been required to travel to Cardiff to attend meetings as an advisor.
He has been credited with helping to bring a new wave of commercial office developments to the centre of Cardiff.
A spokesman for Welsh Conservative leader Andrew RT Davies said: "These revelations raise fresh concerns over the unusual relationship that Labour donor David Goldstone had with the Welsh Labour Government.
"You have to ask if it was appropriate for the taxpayer to be asked to foot the bill for his hotel bills – in the very city in which he was employed to work.
"There are significant questions for the First Minister to answer here. Not least because he appears to be the only Welsh Government adviser to have enjoyed a deal of this kind.
"Mr Goldstone resigned in 2015 following allegations of inappropriate influence over the former minister, and this FOI will only further muddy the waters."
Mr Goldstone resigned as an adviser to the then Minister after Mr Davies wrote to the First Minister urging him to investigate allegations that Economy Minister Edwina Hart may have breached the ministerial code in taking advice from Mr Goldstone.
Mr Goldstone did not respond to a request for a comment.
A Welsh Government spokesman said: "David Goldstone was based in London and was required to travel to Cardiff to attend meetings.
"It is usual practice to pay travel and subsistence costs as part of the terms of appointment for consultants employed by the Welsh Government."
