The daughter of Arthur Scargill is to marry the man who helped close down the last pit in the National Union of Mineworkers' heartland, it was disclosed yesterday.

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, South Yorkshire, where Dr Scargill works as a GP.

Mr Logan said he first met his future mother-in-law, Mrs Anne Scargill, five years ago when she was involved in the Women Against Pit Closures protest.

He arrived at the colliery to find his office door super-glued shut. He studied security video tapes and noticed Mrs Scargill.

Mr Logan described his first meeting with his future in-laws.

''First I was introduced to Margaret's mum - but I already knew her,'' he said.

''That first meeting was quite embarassing for all of us,'' added Mrs Scargill, who confessed she had glued the office door as part of the 1993 miners'campaign.

Mr Logan met Mr Scargill a few days later. ''When I told him he laughed his head off,'' he said.

The couple plan to marry later this year.
