As of my last knowledge update, the record for the highest score in a cricket match was set by Brian Lara of the West Indies, who scored 400 not out in a Test match against England in April 2004. This remarkable innings took place at the Antigua Recreation Ground and remains a landmark achievement in cricket history. Lara's record-breaking performance showcased his incredible batting skills and ability to dominate opposition bowlers. Since then, there have been attempts to surpass this record, but as of now, it still stands as the highest individual score in Test cricket.
