A group called the Genesis II Church is offering up bleach-like chemicals as a miracle cure for cancer and other diseases at a secret event this weekend.

Surrey and Buckingham Trading Standards released a warning due to concerns that potentially harmful products could be available to buy or consume at the event in the county.

The exact location is being kept a secret amid fears Miracle Mineral Solution (MMS) and Chlorine Dioxide Solution (CDS) will be at the "seminar" on June 12 and 13.

The Food Standards Agency has warned MMS and CDS should not be consumed. MMS is sold as an oral supplement which could cause nausea, vomiting and diarrhoea, potentially leading to dehydration, reduced blood pressure and respiratory failure.

CDS is more dilute but can irritate and damage the skin and gastrointestinal tract if swallowed. Both have been touted as a cure for cancer, HIV, hepatitis, malaria and flu.

Richard Walsh, Surrey County Council cabinet member for localities and community well-being, said: "This so-called 'miracle mineral solution' appears to target vulnerable people and those suffering serious illnesses who are asked to pay large sums of money for a product which not only doesn't work but could be dangerous.

"We are determined to protect consumers from misleading claims and deceptive practices and would urge anyone with information about the sale of these products to come forward."

Anyone who is aware of these products being sold should contact citizens advice consumer helpline on 03454 040506.
