The House of Lords has launched a select committee to investigate the adoption process in England and Wales.
The committee, which is chaired by Baroness Butler-Sloss, will look at previous adoption legislation as well as proposed draft adoption legislation.
The Adoption and Children Act (2002) and the Children and Adoption Act (2006) will come under particular scrutiny.
Among issues to be looked at are delays in placing children, increasing the number of adopters and post adoption support.
Social work and social care groups are invited to submit evidence to the committee by 19 July.
Baroness Butler-Sloss, said: “We still have far too many children in the care system who would be far better off being adopted and it is an issue that needs to be urgently addressed.”
