Boris Johnson visited a Subway branch in Uxbridge and got behind the counter to rustle up a sandwich - but he really didn't seem to find it easy.
After fumbling about getting some plastic gloves on, he gazed confusingly at one of the seeded types of bread and asked: "What sort of bread is it? Is it a bap?".
His confusion clearly continued as he followed up with: "Do you get the tomatoes ready sliced?"
Boris didn't actually eat the sandwich himself, explaining on arrival "I've just had a huge load of fish and chips".
But he did take an interest in Subway's growth in sales, contemplating: "What does that tell us about the world? Why is it growing so fast? Is it that nobody has an office canteen any more?"
When asked if Boris would make a good sandwich artist, Greg Madigan, area development manager for Subway in the UK, said: "With a bit more work, maybe."
He added: "It was a full sandwich."
To be honest, we probably wouldn't complain if we got a sandwich with THAT much filling. Talk about getting your money's worth...
