Brendon McCullum tells court of spot-fixing approach by Chris Cairns

New Zealand captain Brendon McCullum has told a court that he was asked to get involved in match-fixing by former international teammate Chris Cairns.

McCullum, 34, told London's Southwark Crown Court that Cairns made the request in a hotel room in Kolkata, India, in 2008, during the Indian Premier League.

According to McCullum, Cairns approached him with the "business proposition" in the room and drew a diagram on a piece of paper explaining how spot-fixing worked.

Cairns, 45, is charged with perjury and perverting the course of justice after saying that he had never cheated at cricket during a libel action he won in 2012.
