Disgraced Australian cricket captain Steve Smith has been dumped as the face of breakfast cereal Weet-Bix after his involvement in ball-tampering.

Smith, who has been banned from the game for a year, had already been removed from the brand's website.

Weet-bix owner Sanitarium said the cheating went against "brand values of trust and integrity".

Separately, financial group Magellan has pulled out of its naming rights sponsorship of Cricket Australia.

While the value of the three year deal was never announced, Magellan's decision to end the contract after less than eight months will cost the sport a reported 20 million Australian dollars (£10.9m; $15.3m).

Meanwhile sportswear maker Asics has dumped Cameron Bancroft, who carried out the cheating in a match against South Africa, and Australian vice-captain David Warner who was involved in the plan to tamper with the ball.

'No option'

Smith, 28, was named as a so-called 'Weet-bix Kid' in late 2015 alongside other Australian sports stars including footballer Tim Cahill and surfer Stephanie Gilmore - and was central to the cereal's marketing campaigns.

But he was axed after a report by Cricket Australia found the captain knew of a plot to tamper with the ball, failed to stop the plan and sought to mislead officials and the public.

"Weet-Bix ambassadors represent our brand values of trust and integrity, and they speak to everything that is good about being Australian," said Todd Saunders, executive general manager for Sanitarium Australia.

"Their role as a 'Weet-Bix Kid' is to inspire millions of Aussie kids to be the best they can be. Based on the ball tampering incident and the findings of Cricket Australia's investigation, we are unable to continue our relationship with Steve Smith."

Weet-Bix is a cereal sold primarily in Australia and New Zealand and is a different brand to Weetabix which is prevalent in British shops.

Magellan's chief executive Hamish Douglass said the ball-tampering in South Africa was "so inconsistent with our values that we are left with no option but to terminate our ongoing partnership with Cricket Australia".

"A conspiracy by the leadership of the Australian Men's test cricket team which broke the rules with a clear intention to a gain an unfair advantage... goes to the heart of integrity."

Airline Qantas, whose logo appears on the Australia team's shirts earlier said it was "very disappointed" by the scandal but has no plans to pull its sponsorship.

IPL contracts lost

While their reputations are in tatters, the financial losses to the individual cricketers goes beyond the fallout of cancelled sponsorship and endorsement contracts.

Smith, Warner and Bancroft are banned from playing international cricket for Australia, and in Australian domestic leagues.

But although they remain eligible for competition outside of Australia, Smith and Warner were also banned from this season's Indian Premier League.

In January the pair were signed to the most lucrative Twenty20 contracts ever offered to an Australian player - reportedly worth over £1m each.
