Film about the exhumation of the body of a revered Catholic Scotswoman to be featured at Edinburgh Fringe Festival

Sinclair was born into poverty in 1900, worked for McVities biscuit factory and was an active trade unionist before she joined the Poor Clares convent in London and worked tirelessly with the underprivileged.

She died of tuberculosis in 1925 and many have since claimed to be cured after offering up prayers to her memory. Sir Jimmy Savile, who backs the campaign to have her canonised, believes that he owes her his life after his mother prayed to her image when he was seriously ill as a child.

Given the title venerable by Pope Paul VI in 1978, her body was exhumed from Mount Vernon cemetery and re-interred in St Patrick’s in the Cowgate, the church she attended as a child, in 2003.

The proceedings, attended only by a select gathering of senior church figures, were videoed and will now be shown publicly for the first time next month. The tour will also include visits to her former home and the sites of her old and new graves.

Father Edward Hone, the senior priest at St Patrick’s, said: “We are going to run the tour for the first time this year as part of a campaign to widen people’s knowledge about Margaret Sinclair.

“Edinburgh already runs a number of ghost tours which are very popular during the festival so we decided to start one following her footsteps.”
