People will doubtless attempt to spin this very human story in wider ways. David Cameron clearly wanted to be present at the creation of a British hero, the catalyst of a feelgood factor whose green shoots pollsters claimed to discern this weekend. But Alex Salmond had to be there too to also claim this as a Braveheart moment. In his young days, the new Wimbledon champion displayed Scottish antipathy towards English football until he acquired greater diplomatic finesse. Yesterday he referred to himself as a British champion while Mr Salmond rather unnecessarily waved the saltire from the royal box. Right now, though, it seems hard to imagine Murray being impressed by anything much except his own victory. The triumph of toughness is the best thing about yesterday’s win.
