Iain Duncan-Smith confuses the roles of "government" with "parliament"

Judge hints at legal hitch that could seriously delay Brexit

With a curious piece of “double talk”, Iain Duncan-Smith argues that Parliament rather than judges should decide in respect of triggering Article 50, but goes on to say that Government must use its “executive powers”, to commence the process. Not for the first time in his checkered political career, IDS is confused and seeks to bully his views onto others as he did during his infamous period as Work and Pensions Secretary at the DWP. His confusion arises either by accident or more probably design, in his belief that “government” and “parliament” are synonymous terms used to describe the mechanism of administering the country. They are not. For the benefit of Iain Duncan-Smith, and any others who may be under such a delusion, Parliament is the House of Lords and the House of Commons combined. Government on the other hand, is and has historically (certainly since the days of the Blair administration), been a small cabal of senior ministers or advisers, led by the Prime Minister of the day, who use their “executive powers” to bypass Parliament to enact pieces of legislation which they believe will be contentious or difficult to pass, should parliament be allowed to debate the matter.

Three of the "Cabal"

On the question of the forthcoming Supreme Court hearing on the governments appeal against the original High Court judgement Duncan Smith argues that, “It is not their job to tell parliament … how they should go about that business, that’s for parliament to decide.” He then goes on to fall over his own tongue by contradicting himself with the comment that, “What the judges will decide on at the supreme court is whether or not the government can use its executive powers to trigger article 50”.

Perhaps I may remind Duncan-Smith that this country endured civil war to establish the supremacy of Parliament over the Monarchy. To replace the tyranny of the “Divine Right of Kings”, with the equally objectionable “government executive powers” undermines the foundations of Parliamentary Democracy in this country.

The closed, almost secret cabal of “government” must never be allowed to use “executive powers”, to circumvent or undermine the supremacy of Parliament.
