Cycling: Bradley Wiggins still in the race for second Tour de France title

Bradley Wiggins: The Team Sky rider says no decision has been taken on Tour ‘leader’ (PA)

Bradley Wiggins could yet target a successful defence of his Tour de France title, despite previously suggesting his focus for 2013 would lie elsewhere.

The 32-year-old became the Tour's first British winner in July, with Team Sky colleague Chris Froome second, and at October's launch of next summer's 100th Tour Wiggins intimated that May's Giro d'Italia would be his main target.

That preference would leave Froome as the logical choice to lead Team Sky in France, but speaking last night Wiggins suggested that winning back-to-back Tour de France titles remains his ambition.

"I don't know what the situation is in terms of leadership, as it stands I'm probably going to try and win a second Tour de France," he said.

"Maybe we'll have two leaders, which is more than likely, I guess. How that's going to work with the team I don't know, that's more [Team Sky general manager] Dave Brailsford's problem to worry about. It's just how we service both mouths. Like I said that's more a problem for Dave to figure out, but my goal is to win the Tour next year.

"Whether that is realised or not I don't know really, we're still in this planning phase, deciding each race, what we're going to do next year, how we are going to go about training to do that."

Meanwhile, the World Anti-doping Agency has "significant concerns" with the focus of an independent commission set up by the UCI in the wake of the Lance Armstrong scandal.

A three-person panel chaired by former Court of Appeal judge Sir Philip Otton and including Australian lawyer Malcolm Holmes QC and Baroness Tanni Grey-Thompson has been brought together to analyse and report on the Armstrong affair and the role of the governing body.

The commission will act as a fully independent external body but Wada has expressed misgivings over its terms of reference.
