Three people accused of mixing horsemeat with beef before passing it off as beef are to be charged with fraud, UK prosecutors have said.

Ulrick Nielsen, Alex Ostler-Beech and Andronicos Sideras will appear in court in London in September accused of dishonestly arranging "for beef and horsemeat to be combined for sale as beef", the Crown Prosecution Service announced today.

The trio have been jointly charged with conspiracy to defraud between 1 January and 31 October 2012 following an investigation led by City of London Police.

Kristin Jones, CPS head of specialist fraud, said: "The CPS has today authorised charges against three men, relating to the sale of mixed beef and horsemeat products which were sold as beef.

"After carefully considering evidence from the UK and overseas, the CPS has decided that there is sufficient evidence to provide a realistic prospect of conviction and it is in the public interest to charge these three men.

"This decision comes after a thorough investigation conducted by the City of London Police in liaison with partner agencies."
