Microscope on match-fixing

Djokovic says he was approached in 2007; British PM wants answers

A bombshell report alleging widespread corruption in tennis cast a shadow over the start of the Australian Open on Monday as officials vigorously denied suppressing evidence of match-fixing.

The BBC and BuzzFeed reported that a "core group" of 16 players who reached the top 50 in the past decade, including Grand Slam winners, had repeatedly caused suspicion but never faced action.
