Malcolm has worked with Anderson since he was 13 years old

Jock Anderson blamed a "total lack of support" from Welsh athletics bosses for his decision to quit after more than 10 years by Malcolm's side.

"Obviously I'm gutted about it. Jock's been there for me since I was 13 years of age," Malcolm told BBC Wales Sport.

"After the Commonwealth Games I'll have to review things and see how I do."

Under Anderson's guidance, Malcolm has developed into a world-class athlete and is one of Wales' brightest medal hopes in Melbourne.

But the 26-year-old and 200m specialist will fly out to Australia next week without his mentor by his side, and will finalise his preparations alongside Linford Christie and Darren Campbell.

It is a shame that it has come to this and we wish Jock and Christian could have come to us with any concerns Athletics Association of Wales director Steve Brace

Malcolm added: "I don't blame Jock for what he has done. He has had no support from the Athletics Association of Wales for so long now that he has just had enough."

Athletics Association of Wales director Steve Brace accepted Anderson's criticisms of the funding crisis in the sport.

But Brace said a lack of a major sponsor meant Welsh athletics had to be run on a tight budget.

"The AAW runs at a deficit and we simply don't have the funding available to financially support coaches," Brace told the South Wales Argus.

"We can help a little but there is only so much money we can have. We are not a WRU or and FAW, we don't have any major sponsors and it is difficult."

Brace added: "We are obviously concerned that Christian is without a coach.

"We want our athletes to travel to Melbourne in the best frame of mind physically and mentally. Christian is one of our best chances of a success in Melbourne.

"It is a shame that it has come to this and we wish Jock and Christian could have come to us with any concerns.

"But this has come completely out of the blue, we've had regular squad meetings and this has never come up."
