A tennis fan is taking legal action against Nick Kyrgios after he accused her of being "drunk out of her mind" during his defeat in this year's Wimbledon final.

Anna Palus said the 27-year-old Australian had defamed her by making "a reckless and entirely baseless allegation".

"Not only did this cause considerable harm on the day, resulting in my temporary removal from the arena, but Mr Kyrgios's false allegation was broadcast to, and read by, millions around the world, causing me and my family very substantial damage and distress," she said in a statement released by her solicitors.

Kyrgios, well known for his outbursts, complained to the umpire during his match against Novak Djokovic, saying that a fan had been talking to him during points.

Asked by the umpire to identify the fan, Kyrgios said: "The one with the dress. The one who looks like she's had about 700 drinks, bro!"

Ms Palus has instructed her solicitors to begin legal proceedings against Kyrgios and said any damages she may win would be donated to charity.

"However, if he is unwilling to do this, I am committed to obtaining vindication in the High Court."

Kyrgios was appearing in his first grand slam final and took the first set against Djokovic but lost his cool as he headed to a four-set defeat on centre court.
