Answer
Shane Warne, the legendary Australian leg-spinner, was surpassed by Sri Lanka's Muttiah Muralitharan in 2007 as the leading wicket-taker in Test cricket. Muralitharan achieved this remarkable feat during the first Test against England at Lord's, dismissing Alastair Cook to claim his 533rd Test wicket and surpassing Warne's previous record of 532 wickets.
