We're left with a leader that is devoid of leadership capacity, lumbered with the charisma of a damp rag, the vision of a mole and all the on-camera tact of a 14 year old pubescent man-child. A sepulchral sod. Goodness knows the manner off-camera. So let me say it again, it's the man, not the House, who's no longer fit for purpose.
Firstly, Northern Ireland is not your normal western liberal democracy. As Mick Fealty said, there exists two worlds in Northern Ireland. One is progressive, cosmopolitan, tolerant, ambitious. The other is a minority that extorts, blackmails and wields arbitrary power over a moderate majority. The politicians are complicit with these economic vandals and thugs.
The working class enclaves in inner-city Belfast have soaring poverty and joblessness rates. Once the voice of hardline unionism, the DUP has become increasingly mainstream and is seen to represent these communities less and less, with a similar process happening on the other side of the political divide.
