The changes mean stopping payments that would have supported children until they left full time education.
Baroness Sherlock, who has also signed the letter, said: “What will happen in practice is that a six year-old who lost her father last year will be supported until she leaves school; if her father dies next year that support would stop after 18 months.”
She went on to say that these cuts were part of an attempt to cut £12 billion off social security. “The Government should not take money away from bereaved children.”
The plan was for a larger initial payment and then payments ending after 18 months.
Bishop Donald disagreed with this move.
He said: “I fully accept that the system needed reform, but those of us who spend a lot of time looking after people in bereavement know that a widowed parent may sometimes have to spend several years giving considerable extra time, attention and care to children. In practice, that may necessitate working only part-time for a number of years while children are still at home.”
