David Cameron is reduced to the role of a spectator in a country that he has been elected to govern. Ed Miliband may be Labour leader, but he is an observer as well. Neither politician has tried to defend the influx of migrant workers, which is understandable because it wasn’t their decision. But they can’t attack it either. As a result, an important issue that is likely viscerally to affect the lives of many British citizens has been sucked out of public discourse and the democratic arena. Labour, Lib Dem and Conservative are united in impotence and uselessness.
