ONE of Scotland’s richest women has been accused of employing a legal “attack dog” to challenge Judy Murray’s controversial plans for a multimillion-pound tennis and golf centre.

Ann Gloag, the 73-year-old co-founder of Stagecoach, owns a landowning company adjacent to the planned Park of Keir development on the outskirts of Dunblane.

The businesswoman is the only director of Arnbathie Developments, which wants to build 129 “self-contained and discrete” houses on its own site nearby.

Ms Murray and the King Group of developers have earmarked a 12-court indoor and outdoor tennis centre, trainer golf course, a museum dedicated to her son Andy and Jamie’s successes and country park.

The proposal would be funded by 19 luxury homes and a 150-bedroom hotel, gym and spa close to the M9 and A9 junction.

Stuart MacGarvie, a chartered town planner representing Ms Gloag’s company, told a public inquiry in the Perthshire town yesterday that Ms Murray’s proposals failed to meet the criteria for a concept known as “enabling development”. This is where a construction that would otherwise be rejected is allowed, because it is the only means possible to fund something regarded as of public benefit.

Mr MacGarvie said no off-site locations for the “enabling development” had been put forward by Mrs Murray’s Park of Keir Partnership group. He added the tennis centre, on greenbelt land, was “not sited in a sustainable location”.

He was asked by Mrs Murray’s solicitor, Neil Collar why it was in Mrs Gloag’s interest to object to Mrs Murray’s proposal.

He added: “Mrs Gloag doesn’t live on the site. And she doesn’t live in the local area, does she?”

Mr MacGarvie replied: “Depends how local, but no.” Mr Collar: “So why would Arnbathie object?”

Mr MacGarvie replied: “I have significant concerns about the impact of development on that site.”

Mr Collar suggested the reason why Mrs Gloag’s company had focused on the issue of “enabling development” was because if the Murray plans were refused on that basis it would not set “an awkward precedent” for her own site.

Mr MacGarvie replied: “I disagree. I can’t accept that premise.”

He added: “Our concern is the extent of this development on the greenbelt.”

Mr Collar said: “You’ve not provided any comprehensive assessment to this inquiry.

“Your evidence is really a Trojan horse, to deliver Mr Innes [Colin Innes, solicitor for Arnbathie] as an attack dog, to give him the opportunity to undertake extensive cross-examination.”

Mr Innes labelled Mr Collar’s question as “completely, utterly outrageous and unprofessional” and said Ms Gloag had been smeared by the allegation.

The inquiry has now ended and a final decision is expected within months.
