This Saturday marks Labour’s 100th day in office. But they are unlikely to be popping champagne corks in Downing Street – even if Lord Alli offered to pay for the Dom Pérignon. This has been a disheartening time for the government and those who wished it well. The promise of dramatic change has been overshadowed by a series of errors, misjudgments and scandals that one would associate more with an administration in its dying days than a government enjoying a fresh mandate, a massive majority and an absent opposition.
