The number of children who go missing in the UK each year is a staggering 140,000. Working on behalf of P.A.C.T. (Parents of Abducted Children Together), we realised this is more than could fit in Wembley Stadium. So we made a TV, Web and Print campaign about it, sponsored by The Sun, which runs at Wembley Stadium on England International match days and at other topical times of year.
