Davidson's portrait of German Chancellor Angela Merkel featured on the cover of Time magazine last year. Well-known figures who have sat for him in recent years include Liam Neeson, Jamie Dornan, Ed Sheeran, Brad Pitt, Tyson Furey, Glen Hansard, the late Rev Ian Paisley and Martin McGuinness.

The painting was commissioned by the Chairman of Co-Operation Ireland, Christopher Moran, to mark Queen Elizabeth's 90th birthday year and he involved an Irish artist to symbolise the bond among neighbours. Guests at the event will include the Tanaiste, Frances Fitzgerald and Northern Ireland’s First Minister and Deputy First Minister, Arlene Foster and Martin McGuinness.

Colin Davidson was the artist behind The Silent Testimony Project which featured 18 individuals from North and South who were caught in The Troubles and was praised for its extraordinary empathy.
