Eurosceptics – and those such as Ukip who are far beyond scepticism – have long claimed that one of the main reasons for us to renegotiate our relationship with the EU or to leave it altogether is the amount of sovereignty we have surrendered.
That our own civil servants spend nearly half their time implementing Brussels regulations demonstrates this loss of sovereignty in stark terms. It is a wake-up call to the Prime Minister over Europe and the unchecked power of bureaucrats not only in Brussels but also here in Whitehall."
