Prince Harry's controversial autobiography, 'Spare', is described by its publishers as a "landmark publication" which chronicles his journey with "unflinching honesty, revelation, self-examination, and hard-won wisdom about the eternal power of love over grief" as he married Meghan Markle in a lavish ceremony at Westminster Abbey before a dramatic and damaging split from the royal family.

And after a blaze of publicity earlier this year in Largs, with both windows of WH Smith featuring giant posters of the Prince, the best-selling book was spotted on sale for only £4.99 in the Red Cross Charity shop in Largs.
