After six years of delicate negotiations, and then nearly two more spent actually painting the work, Lucian Freud, lauded as Britain's greatest living portrait artist, today formally presented the Queen with this, her latest portrait. The result? An unforgiving, warts-and-all vision of Her Majesty in which she looks distinctly grumpy. Freud travelled to Buckingham Palace from his west London studio with the painting, which will be a star exhibit of the inaugural exhibition at the new Queen's Gallery from 22 May.
