A poet has won his third Wales Book of the Year award for his writings on Brexit and the environment.

Robert Minhinnick, who grew up near Bridgend and studied in Aberystwyth and Cardiff, also won the Roland Mathias Poetry Prize.

His book, a collection of poems called Diary of the Last Man, was described as "environmentalism turned into elegy".

Minhinnick accepted the award and a £4,000 prize at a ceremony run by Literature Wales in Cardiff on Tuesday.

The poet also received a specially commissioned trophy designed and created by the artist Angharad Pearce Jones and presented by the Chair of the Arts Council of Wales Phil George.

"This is environmentalism turned into elegy," said judge Carolyn Hitt.

"It is so powerful, so political. These are serious poems for serious times that will stay with you and make you think about what we are doing to the planet."

Minhinnick's poems have twice won the Forward Prize for best individual poem, and his winning collection, Diary of the Last Man, was shortlisted for the T S Eliot prize last year.
