A FATHER taking legal action over the MRR vaccine is calling for Britain's Chief Medical Officer, Sir Liam Donaldson, to step down. Gareth Fairhurst, from Wigan, who was handing in a 150,000-signature petition at Downing Street today, says the Government is breaching his human rights by not offering single inoculations for children against measles, mumps and rubella.

Mr Fairhurst has more than 150,000 signatures in his support.
