The LTA said last year that Murray should focus on winning Grand Slams
British number one Andy Murray insists he has not abandoned the British team despite pulling out of the forthcoming Davis Cup match against Lithuania.
The 22-year-old says he is missing the tie in March so younger players can gain more international experience.
The Scot said it was "unfair" to criticise him when other top players had also skipped Davis Cup matches.
"I don't think it's a case of me abandoning Great Britain. I've played a lot of matches for them," he said.
"You've got to do what is right for your tennis. That period of the year just before Indian Wells and Miami is very important for me.
"I've got a lot of ranking points to defend. I think it's the right decision."
Murray, who will play for Team GB alongside Laura Robson at the Hopman Cup in Australia this week, pointed out that Roger Federer, Rafael Nadal and Novak Djokovic have missed Davis Cup games for their respective countries.
"It would be a bit unfair to single me out. A lot of players better than me have missed Davis Cup matches," he said.
Murray's decision is set to give the likes of Jamie Baker and Dan Evans the chance to prove their mettle.
"We are in quite a low group now. When I do play and we lose, I don't feel like it benefits the other players.
"It think it's been 10 years or something since a British player outside myself, Tim (Henman) and Greg (Rusedski) won a live Davis Cup rubber.
"It's time for the guys to get used to winning in the Davis Cup, rather than having so much pressure on them every time they play," he said.
Murray, who is number four in the world, hinted after Great Britain's relegation to Europe/Africa Zone Group II in September that it might be time to give other players an opportunity.

And he was supported by Lawn Tennis Association chief executive Roger Draper, who said he would be happy for Murray to miss future Davis Cup matches as the Scot focuses on trying to win Grand Slam titles.
"That's what I want to do, but this is one of, if not the toughest era in tennis. You can play great and not win right now because of how good the other players are.
"I'll try my best to win a Grand Slam, that's my goal, but I still think you can be successful in tennis even if you didn't win one.
"Having said that, I would be disappointed if I didn't," Murray added.
