The 2017 semi-finalist and 30-year-old's withdrawal was confirmed by the All England Lawn Tennis Club (AELTC).

Britain's number one women's tennis player must now self-isolate for 10 days.

"A member of Johanna Konta's team presented with COVID-19 symptoms this morning, and immediately isolated and undertook a PCR (polymerase chain reaction) test in accordance with the Championships' testing protocols," read the statement.

"A positive result was returned which resulted in the AELTC, together with Public Health England, identifying Johanna Konta to be a close contact.

"In line with Government legislation, she is required to self-isolate for 10 days and therefore is withdrawn from the Championships.

"Both Johanna and her team member had tested negative on all their previous tests undertaken within the Championships' protocols.

"Both individuals were advised of the positive test and close contact classification and are now self-isolating for the next 10 days."

Konta was due to start her campaign tomorrow against Kateřina Siniaková of the Czech Republic.

Wang Yafan of China will instead play the Czech player in round one.

Konta won her first title for four years in a warm-up event at the Nottingham Open earlier this month, showing her form going into the third Grand Slam of the year.

Due to the COVID-19 pandemic, Wimbledon was cancelled in 2020.
