Political commentator Rupert Myers has told talkSPORT that Owen Smith's challenge for the leadership of the Labour party could be scuppered by his previous role as a pharmaceutical company lobbyist.
Smith was in charge of corporate and public affairs, corporate and internal communications, and public affairs for the British arm of Amgen between 2008 and 2010, when the pharmaceutical giant was being investigated for its marketing of the anaemia drug Aranesp.
The company was fined $762m (£580m) in 2012 for illegally promoting the drug to cancer patients in a way that increased the likelihood of their deaths.
"It's amazing how Jeremy Corbyn's past appears to slither off him like oil," Rupert Myers told Sam Delaney.
"Sadly I think Owen Smith is going to have this hung around his neck by the Corbynistas who are very quick to forget everything Corbyn's done wrong.
"Owen Smith isn't a name or a face to set the world alight, anyone who boasts about being normal is to be treated with a fair degree of scepticism and alarm."
