Eastleigh MP Chris Huhne has backed a Commons motion supporting the use of the combined MMR vaccine.
Mr Huhne said, "The re-emergence of measles and the loss of life and long-term health problems which will afflict children as a result of the decline in the vaccination rate are of great concern."
"Every step must be taken to ensure that children are protected from this potentially life-threatening illness."
