Presumably, the Labour leader's handlers arranged this photo op, what with the Olympics nearly upon us and the perennial requirement for political leaders to be seen as dynamic and virile. But the gap between idea and reality can be a right bummer, as T.S Eliot once said.
Actually this snap may flatter Ed. I speak as one who has actually seen him running. It was a striking and memorable sight. Several years ago I was strolling down a hill leading to Wembley stadium, where U2 were playing a concert, when Ed hurtled past, perhaps late for some pre-gig hospitality or - who knows? - eager to secure a place at the front. Although he was clearly moving forward, every part of his body seemed to be moving on its own trajectory. It was as if his limbs had been gathered up separately and hurled down the hill.
The sad truth is that Ed Miliband, like many of us, was born to walk.
