Today I did a quick allez-retour to London primarily to meet up with an FCO official with overall responsibility for relations with the EU institutions. The discussions, all cuisine interne, were useful and productive. I walked from St Pancras to my rendezvous, near Millbank. This was not to avoid picking up swine flu in the Underground but because, after four days spent sitting in back-to-back meetings, I badly needed some exercise and fresh air. (In any case, little good did it do me – I went back in the evening with a cold.) Walking through Bloomsbury, I was hit by a wave of nostalgia. As a teenager, when I went ‘up to town’, I always arrived at Euston and headed down towards the West End through Bloomsbury. Europe has so many beautiful cities. It’s just a shame you can only live in one of them at a time.
