It was the kind of spring day in Mayfair they used to write songs about. Beneath a cloudless sky daffodils were blooming in Hyde Park. Blue and yellow, the colours of Ukraine.
Everything seemed to be blue and yellow: the Euro Car Parks sign, the police vans and motorcycles, and the hi-vis jackets their occupants wore, but most obviously the hundreds of flags held aloft by those gathered beneath the Park Lane Hilton for the London Stands With Ukraine march to Trafalgar Square.
