Fred and Peter Done, the owners of major British bookmaker Betfred are making millions from a business that provides services to taxpayer funded clients including NHS trusts treating gambling addiction.

The damning revelations were published by the Guardian, which is reporting that the billionaire Conservative party donors Fred and Peter Done own a company called Health Assured – a company which has “dozens of government contracts” to provide staff with wellbeing programmes.

The Guardian alleges that Health Assured’s British taxpayer-funded clients include “multiple NHS trusts” that also treat gambling addicts. The company also has contracts with the Houses of Parliament, local authorities and the Ministry of Defence.

The newspaper says that the Done brothers have made £5.2m in dividends from Health Assured over the past three years alone.

Unsurprisingly the news has drawn furious condemnation from across the board, with Labour’s shadow health secretary, Jon Ashworth, accusing the Dones of profiteering from gambling addiction, and said the situation is an unacceptable conflict of interests.
