A series of deeply personal unpublished poems by Ted Hughes has been discovered and will be auctioned at Sotheby’s next week.

The previously unseen poems were written shortly after the poet’s partner, Assia Wevill, killed herself and their daughter, Shura, in 1969, six years after the suicide of Hughes’s first wife Sylvia Plath.
