More than 30,000 children were missing from schools in England and Wales for substantial periods of time in the 2014-15 academic year, local education authority figures show.

Of these, almost 4,000 children could not be traced by the authorities.

The National Children’s Bureau said some may be at “serious risk” of abuse and exploitation, including forced marriage, FGM and radicalisation.
