Story highlights Kremlin speaks out over Maria Sharapova doping scandal

Sharapova failed drugs test at Australian Open

Made admission in press conference

Could face a ban of up to four years from sport

(CNN) She's the $195 million athlete at the center of a failed drugs test scandal but tennis star Maria Sharapova isn't lacking for some heavy hitting support.

"Attempts to politicize sports, attempts to add character to sports of some kind of political instrument for achieving some aims, are destructive for sports, for international sports, and are unacceptable and inexcusable," presidential spokesman Dmitry Peskov told reporters on Wednesday.

The five-time grand slam winner revealed Monday that she had tested positive for a recently banned substance --meldonium -- at January's Australian Open. The 28-year-old Russian will be provisionally banned by the International Tennis Federation (ITF) on March 12.

Sharapova's admission comes after allegations of state-sponsored doping were made against the All-Russia Athletic Federation (ARAF) last year following a report from the World Anti-Doping Agency (WADA).

It led to ARAF being suspended from international competition last year by the International Association of Athletics Federations and plunged their chances of competing at the Rio de Janeiro Olympics into jeopardy.
