Dr Margaret Scargill has announced her plans to marry former Grimethorpe Colliery under-manager James Logan.
Mr Logan, 42, is now business manager at the Ashville Medical Centre, in Barnsley, where Dr Scargill works as a GP.
He told yesterday how he first met his future mother-in-law, Anne Scargill, five years ago when she was involved in the Women Against Pit Closures protest.
He arrived at the colliery to find he could not get into his office because someone had super-glued the door shut.
He studied security videotapes and saw Mrs Scargill sneaking along a corridor with a tube of glue in her hands.
The couple plan to marry later this year.Reuse content
