If you’ve got a spare hour or need refuge from the tourists in central London nip into the National Portrait Gallery. Nip in, she says, it will undoubtedly be just as rammed. As of Friday I’m staying south of the River.

But if you are willing to throw some elbows among the school parties and sports enthusiasts, then this will be your reward.

I wish I had the unfathomable skill and genius to create art like this. But as a metamorphosis into Da Vinci is unlikely, I’m happy to stand back in awe.
