Yesterday, during an evidence session of the Education Select Committee, Lucy repeated her call for a fundamental review of the care system in England.
Lucy also pressed the Children's Minister, Nadhim Zahawi, on criticism of Sir Martin Narey and Mark Owers's independent report on foster care in England, as well as the growing number of children entering the care network.
