Jamie Murray has launched a withering attack on Tennis Scotland's failure to capitalise on the success of his brother, Andy, and criticised the governing body for a lack of "vision".

On the very day TS took steps to see to rebuild their administration following the recent, joint resignation of their president and vice president, the timing of the intervention by a member of the first family of Scottish tennis seemed far from accidental.

Out-going president Ian Conway and vice president Jacqui Duncan had, in their joint resignation letter, cited concerns about the possibility of "cronyism" and lack of transparency in executive decision-making at the Edinburgh-based body.

Murray, a Wimbledon doubles champion and elder brother of Wimbledon and US Open singles champion Andy, as well as the son of British Fed Cup captain Judy, has now made his feelings clear regarding the performance of those executives.

"It's so disappointing that nothing has been done to capitalise on Andy's success and grow tennis in Scotland. Once in a lifetime opportunity!" he wrote.

"Only two indoor courts built in past six years! And member of admin staff promoted to head up performance. What is going on at top of the tree?

"You need vision and strong leadership to grow the game. Great to have role models but you're only as good as your grassroots. So frustrating to see."

A Tennis Scotland spokesperson responded by claiming the body has made significant strides, generating a 51 per cent increase in the number of members using Scottish-registered tennis venues over the past five years and spending more than £3.5m on more than 30 initiatives including the creation of more than 70 new courts and the refurbishment of many others.

"This has afforded thousands of people the opportunity to play tennis at a local level for the first time," he said.

"2,169 schools across Scotland have received teacher training and tennis equipment packs to provide for continued delivery of tennis during curricular and extra-curricular hours.

"While we would, of course, like to see more indoor tennis projects completed in Scotland, we also have to recognise that securing multi-million pound partner funding during the recent recession has been a challenge that is not restricted to tennis.

"Tennis Scotland is in discussion with partners in St Andrews, East Kilbride, Inverness, Edinburgh, Galashiels and Dumfries to look at the feasibility of potential new indoor facilities and other indoor projects such as Gleneagles are already confirmed.

"If Jamie has concerns, which he obviously has, we would welcome the opportunity to sit down with him at any time to discuss his input moving forward.

"As a role model for youngsters taking up the game, his views are obviously important and we would be keen to hear them. We did recently appoint an Interim Head of Performance, who has substantial experience in performance systems, an appointment that was made with the full support of our Board and funding partners (LTA and sportscotland)."

Andree Hawke was announced as interim vice president of Tennis Scotland yesterday, and she appeared to suggest that it is club volunteers rather than Tennis Scotland employees who need to do more to help the game grow.

"It has to be remembered that it is the Tennis Scotland staff who shoulder most of burden and that volunteers, such as myself, can only try to work with them and make their lives easier," she said.

Few are better placed to offer an assessment of the current situation than Leon Smith, Britain's Davis Cup captain. As part of the shift envisaged by respected Australian director of player development Bob Brett, he has been freed up to spend two to three days a week near his Edinburgh home, working on a more hands-on basis with the best Scotland has to offer.
Across the two elite programmes in Stirling and Merchiston Castle, Edinburgh - headed up by his brother, Toby, and South African coach Marcel du Coudray respectively - he feels there finally is a crop of teenagers coming through capable of carrying on Murray's crown, but declined to place additional pressure on certain individuals. 
Two Scottish boys are currently ranked No.1 in Britain - Aidan McHugh at Under-14 level and Ewan Moore at Under-18 level - while the likes of 13-year-old Jacob Fearnley, Cameron Bowie, 15, and Alex Mikheev, 12, are also highly-rated. Four Scottish teenagers also graced last year's girls singles at Wimbledon - Maia Lumsden is currently practising in Amsterdam, Anna Brogan is in Florida with Anastasia Mikheeva and Isabelle Wallace.   
"We have a good bunch of kids in Scotland," said Smith, "and you'd hope so. There should be a legacy of what Andy Murray is achieving and has achieved. There is one boy in particular I think will be one of the best around. He can be very good. But there should be more kids in Scotland playing and wanting to become the next Andy Murray."
