The Tories (and occasionally others) are currently banging on about the dangers of a Labour “supermajority” without defining what it is.
Of course there is no such thing as a “supermajority” in the House of Commons – a vote passes (or fails) when it gets more votes in favour. Whether that vote gets a majority of one or 100 is irrelevant.
There is a danger with a huge majority though; a lesser danger than allowing the Tories to remain in government or even opposition. But a danger never the less.
A huge majority allows a government to pass laws with less risk than would otherwise be the case. Every so often we head of MP “rebellions” when MPs of the government’s party vote against that government’s wishes.
When a government wishes to pass a law that is on the extremes, they are more likely to encounter a rebellion. And a rebellion was more likely to succeed if the majority is slim.
Thus with an overwhelming majority, the government has a better chance of getting more extremist legislation through and into law.
