A newly discovered self-portrait of a coal miner turned prolific artist is being displayed at an exhibition.Norman Cornish, from Spennymoor, County Durham, was known as the last of the "Pitman painters", who created artwork depicting everyday life.

A previously unseen self-portrait was discovered when conservators at the Bowes Museum in County Durham removed the back board of another one of his paintings.The sketch has become part of a exhibition there called "Kith and Kinship", which explores life in the north as depicted by Cornish and LS Lowry.Cornish spent 33 years working in mines before

The Bowes Museum’s conservator Jon Old, described the discovery as "magical".The new painting was uncovered during conservation work to Cornish’s painting "Bar Scene", and shows the artist in his younger days.

Mr Old said: "The painting had a back board set into its stretcher that appeared to be resting on the back of the painting, which I thought was unusual.

"So, I decided to remove the board to see if it was affecting the painting, and to my surprise it revealed this wonderful other painting on the reverse, which was quite magical.""The US administration respect and understand that we have high standards to support British farming, and to support British consumers, and we're not going to be relaxing those standards," she said.

Many American farmers use growth hormones as a standard part of their beef production, something that was banned in the UK and the European Union in the 1980s.The US has previously pushed for a relaxation of rules for its agricultural products, including beef from cattle that have been given growth hormones.

Farmers in the UK warned ministers last week not to dilute British food standards, saying the use of hormones in rearing livestock cannot be accepted.Shadow chancellor Mel Stride said the Conservatives would "expect" Reeves to stick to agricultural standards "but let's see the detail as and when there is a deal".
