Horsemeat scandal: Four products off Westminster menu

The House of Commons has withdrawn four Brakes beef products from its catering outlets while tests are carried out for horse DNA.
A spokesman said: "Tests on two of the four items have been completed so far; both tests have concluded negative for equine DNA."
It follows an announcement by the Food Standards Agency that tests for horsemeat in processed meat products are being expanded.
Shadow Environment Secretary Mary Creagh said the Commons withdrawal shows "the difficulties of people getting reassurances and then perhaps, as test results come in, finding that maybe they should be withdrawing things on a precautionary basis."
