Mr Tucker said: "We know my uncle was a great admirer of Burra's – but my dad thinks his brother may have also travelled to the area for work."He worked as a labourer and, in later years, travelled around the country making deliveries to building sites. It's also just possible he was visiting the area on his way to St Ives."

Mr Tucker has written a book about his uncle, The Secret Painter, in which he describes how his uncle, who was also a boxer, had a distant and unfulfilled ambition to live in St Ives.About 400 paintings and thousands of sketches came to light after Tucker's death and it was hailed as an important discovery in British art.His scenes depicting the streets and pubs of north-west England attracted comparisons with LS Lowry.

An immersive art installation that invites people to "disappear" inside a mirrored box to understand life with chronic fatigue syndrome, is coming to the West Country.Created by Bristol artist Alison Larkman, Mirrorbox plays messages from ME and long Covid patients explaining why a particular location is special to them, and why their condition means they cannot be there themselves.

Ms Larkman, who has ME, said the concept came from "the idea of taking up space, of being seen and heard but also being invisible at the same time".

The initiative, titled 'I would be here if I could', has seen the Mirrorbox travel all over the country and it will be in Bristol and Glastonbury in the coming weeks."I tried to calm myself and tried to keep going."

The first set headed to a tie-break after only one unconverted break point for the favourite, but it was Shelton who initially gained the upper hand.With the crowd roaring their approval as the pair played out a number of stunning points that saw both players at the net, Alcaraz was forced to stave off three set points.
