Britain's top tennis players have voiced strong criticism of Wimbledon's new electronic line calling system, with both Emma Raducanu and Jack Draper claiming the technology has made incorrect calls during their respective matches at this year's Championships.

Jack Draper became the latest Brit to crash out of Wimbledon when he was beaten in four sets by Marin Cilic on Thursday, but he is still hopeful of success for the home contingent

There are 23 British singles players in the main draw and 14 are in action on Monday. Raducanu, who has been suffering from a back injury, will start her campaign against Welsh wildcard Mimi Xu. No.4 seed Draper plays Argentine Sebastian Baez on Tuesday.
