Did a change in policy spark the horsemeat scandal?

One of Britain's most prominent food scientists has told ITV News that recent changes in regulations sparked the horsemeat scandal. Dr Mark Wolfe, worked for 25 years as a government food Scientist - including The Food Standards Agency.

Today he told us that a change in rules "must have contributed to a large extent to this situation". Dr Wolfe says a shift in policy last year meant a type of burger meat produced in the UK could no longer be used, forcing producers of value meals to buy overseas.

The policy change did not only effect beef - but also lamb, so Dr Wolfe also believes those products should also be checked.
