The England and Wales Cricket Board (ECB) is in discussion with Test coach Brendon McCullum over his association with a betting company.

The ECB’s anti-corruption codes prohibit players, coaches and officials from participating in or encouraging betting on matches.

“We are currently exploring the matter and in discussions with Brendon around his relationship with the Cypriot-based betting company, 22Bet,” an ECB spokesperson said. “We have rules in place around gambling and will always seek to ensure these are followed.”

Although McCullum’s association with 22Bet India, a Cyprus-registered online bookmaking company, began before the former New Zealand captain took over the England job last year, he has been seen in the betting company’s recent YouTube adverts around this year’s IPL.

His agent Simon Auteri told The Times, London: “We are speaking to the ECB about this. I am not going to comment on anything. We are working through it.”
