It seems that the Brexit issue is driving British politicians into the mad house, or at least into the arms of Big Pharma drugs. It is difficult to be so continuously traitorous, as the poison flows freely:

“Brexit madness” has overtaken the House of Commons according to one senior MP, warning about the rise in mental health issues among parliamentarians. Education Committee chair and senior Brexiteer Robert Halfon has said that “It feels like the Commons is having a collective breakdown — a cross between Lord of the Flies and One Flew over the Cuckoos Nest.” In comments reported by London’s Evening Standard, the Tory MP went on to say, “People are behaving in ways that were unimaginable even just a year ago, whether they be Remainers, Leavers or in-betweens. The Brexit madness has affected us all”. Mr Halfon is not the only Member of Parliament to express such concerns, with one female MP telling The Sun that parliament had become a “boiling pot of mental ill health”. One male MP was reportedly reduced to tears after finding out he won’t be able to go home to see his children next week, due to the cancellation of MP’s Easter recess. Comments made to a BBC radio programme by Members of Parliament claim Brexit was leading to politicians drinking more and avoiding people. One said it was “taking an emotional toil”.

     This is because the traitorous pollies have done all that they can to sink Brexit and brainwash the people who voted for exiting the EU. Nevertheless, 92 percent of voters feel betrayed by the government’s handling of the issue.”

“More than nine in ten (92 per cent) Leave voters feel ‘betrayed’ by the way the government has handled Brexit, while two-thirds of all voters feel the same. The ComRes poll, commissioned by the ‘Leave Means Leave’ group and published in The Sun on Monday, also found that 60 per cent of all voters, both leave and remain, said that Brexit had damaged their trust in politics. The poll also found that 57 per cent of Britons believe that the UK should be leaving the EU on World Trade Organization (WTO) terms instead of delaying Brexit.”

     The answer is that Britain is a democracy in name only and if the people somehow manage to vote for that which the ruling elites do not like, then it is the people who must be re-educated. These articles say much the same on this:

“Brexit campaign leader Nigel Farage has told Breitbart London’s James Delingpole that he is ready to keep fighting for Brexit, and despite the ongoing betrayal of the 2016 vote by the British political establishment he remains upbeat. Comparing Brexit — the political and constitutional revolution required to untangle the United Kingdom from 40 years of integration with the increasingly centralised and autocratic European Union — to some of the other great political upheavals in British history, Mr Farage said he was ready to fight the next election.”

     The battle against the globalist forces of evil is humanities’ most epic war, and it will not be over quickly, since the EU forces make the bad guys in Lord of the Rings look like Sunday school teachers.
