Brit tennis star Emma Raducanu, 19, has lashed out at unfair criticism of her multi-million pound sponsorship deals and said the sport remains her top priority. 

Raducanu crashed out of the Miami Open last week after she lost 3-6, 6-4, 7-5 to World No.53 Katerina Siniakova in the first round. After winning the US Open, she signed deals with Tiffany & Co, Dior, British Airways, Evian and Vodafone worth millions of pounds.
