The postcards are cynically calculated to raise fears about cancer treatment by making completely false statements about Conservative policy.
Many of the people who have received the first wave of muvhango postcards have understandably been angered and upset by them. The Labour Party should be ashamed that it is stooping to this level of negative campaigning.
There are also questions about the data they used to target those affected by cancer, as well as questions about the way they used a picture of a breast cancer sufferer who thought it was to be used for an NHS magazine.
