It was a right-wing Tory, attacking a 1970s Labour government, who came up with this phrase, a great starting point when considering the flaws in FPTP, a system used in very, very few democracies - and not even for the many other UK non-general elections.
THE ELECTIVE DICTATORSHIP
Lord Hailsham was condemning how a party with a Commons majority could essentially rule free if any effective opposition.
The Tories didn't win over 50% of votes in 2019. There is a clear anti-Brexit majority from the election vote. Yet they have a massive Commons majority, so the only way they'll face any effective opposition will not be in parliament (though the Lords might pose some temporary barriers for them to simply knock down).
Instead, the Supreme Court is one of three avenues of potential opposition or limits on their decision-making. The majority of UK citizens will not have any effective voice in their parliament for the next five years. Scottish voters have already, 1 day after the election, been warned that their overwhelming pro-independence SNP vote is meaningless. They will not get the second independence referendum they have democratically mandated the SNP to pursue. They will not get a second Brexit referendum either despite the huge pro-remain majority. They instead will be dictated by English MPs.
Unless the Supreme Court rules that an independence referendum must be held because of the terms of the Act of Union and the amendments that set up devolved government.
The 1980s saw Scotland erupt in fury at a similar situation. They overwhelmingly elected Labour MPs, but were ruled by an extreme right-wing Tory government under Thatcher. When she imposed the poll tax, a rather unsubtle attack on the poor, there was immediate civil unrest. The street protests were so huge and prolonged that it would be a key factor in the Tories kicking her out and replacing her with the moderate John Major, who quickly scrapped the poll tax. I predict Scotland will see scenes like those in Barcelona/Catalonia, mass protests over the denial of an independence vote.
The third avenue of limits on a government with no meaningful opposition within parliament comes from international relations. Corbyn revealed the secret negotiations over the NHS with the US. Various Tories have been giving speeches for years on how Brexit gives Britain the chance to become an ultra-low corporate tax centre - a tax haven. I predict the EU will get tough with the UK on post-Brexit trading rules. And the USA will trample over British business and public sector in any negotiated deal given the huge difference in power.
2019 ELECTION - THE NUMBERS
Green MPs elected in yesterday’s general election represented more than 850,000 votes while SNP MPs represented under 26,000, according to figures from the Electoral Reform Society.
More than 330,000 votes were needed to elect a Liberal Democrat, compared to 50,000 for Labour and 38,000 for Plaid Cymru and Conservative candidates.
Meanwhile, the Brexit Party won more than 642,000 votes but failed to get any representatives in the House of Commons.
Overall, the Electoral Reform Society claims that 45.3% of votes did not get any representation, because of the number of voters who didn’t support the winning candidate.
