Alexis Jay officially retired two years ago - not that you'd notice. In 2013 she stepped down from her role as Scotland's chief social work adviser [and started] digging up horrific claims of child sexual exploitation in Rotherham. She moved on to sort out Northern Ireland's safeguarding children boards. Last week ... she joined the panel of what has been described as Britain's most complicated and wide-reaching statutory inquiry ever. The independent inquiry into child sex abuse (IICSA) is expected to take five years investigating claims of abuse in faith and religious organisations, the criminal justice system, local authorities and national institutions such as the BBC, NHS and Ministry of Defence. Jay was one of the first names confirmed as part of the panel. The inquiry had ... a rocky start, losing the support of victims very early on, along with its first two chairs, who were found to be too close to the establishment figures they would be investigating. But Jay [is], "passionately committed to it taking place and to the victims and survivors, and to get justice and truth out of the process," she says. Almost a year on from the televised press conference at Rotherham football club that made her name, Jay still can't believe the rumpus her report caused. "I knew it was going to be significant, but not quite on the scale it was," she admits. For victims, she represents the hope that the statutory inquiry will not be another whitewash.
