Santa Claus is calling on children to help him find the best Christmas gift.
People are invited to St Ann's Shopping Centre, in Station Road, Harrow, to test toys for those who have made it onto the "nice" list.
Centre manager Pieter Strombeck said: "This is a very important job but we are sure the children of Harrow are up to the job."
Families are invited to the centre from 11am to 4pm.
