It is now an accepted fact that vitamin D deficiency is a growing problem in Britain and the child bone disease rickets has returned.

But questions have been raised over whether a lack of vitamin D could also be a factor contributing to Sudden Infant Death Syndrome (Sids) and possibly miscarriages of justice involving allegations of child abuse.

This programme has spoken to a number of eminent doctors who believe it could be and are calling for a review of cases to investigate if vitamin D deficiency played a role.

The Today programme has learned of two surveys in separate hospitals in which vitamin D deficiency was found in 75 infants and is thought to have caused the deaths of five.

Andrew Hosken has been investigating the new allegations.
