David Cameron says that Russia’s annexation of Crimea ‘will not be recognised’. Ukraine’s Prime Minister Arseniy Yatsenyuk promises that ‘we will take our territory back’. They are both misguided. Let Crimea go: it will be the making of Ukraine and the end of Vladimir Putin. Without Crimea, there will never again be a pro-Moscow government in Kiev. Ukraine will have a chance to become a governable country — a strongly pro-European one with a Russian minority of around 15 per cent.

I wish people would stop trying to raise my awareness. I can’t so much as surf the web or stroll a high street these days without being accosted by one of the aware, who is always hellbent on making me as aware as he is, usually about some disease or, if you’re really lucky, the rifeness of child abuse. The army of the aware are everywhere, covered from head to toe in awareness ribbons, their arms weighted down by awareness bracelets, their aware brains bulging with scary stats about Aids, rape, breast cancer or boozing that they are desperate to impart to us, the blissfully unaware.

In a valedictory interview, Sir David Nicholson was quite frank about the state of the health service that he has run for the last eight years. ‘In its current form,’ he declared, ‘the NHS is unsustainable.’ It is hard to imagine Simon Stevens, who takes over as NHS England chief executive this week, having to say that when he leaves. His friends know him as an experienced reformer, a policy expert and a radical. His CV causes some suspicion in Tory circles — he is a former adviser to Tony Blair (I’m also guilty in that respect) and was a co-author of the last Labour government’s health reforms — but that is precisely why he will be so valuable to David Cameron now.
