The question 'how difficult is it to remove the government from power?' was a test applied by Tony Benn, a British MP to offer a measure of how strong democracy is an any state.
For the countries we live in - UK, Australia and New Zealand - the answer is straightforward. We hold regular and frequent elections and the majority in a fairly contested poll form a government for a while. Apply the test to Russia, China, North Korea, Myanmar, Cuba and numerous other states and the answers are very different.
Now, something I hope will cheer up Bradskii: there is a lot of 'Brexit regret' in the UK. Even hardline Brexiteers are admitting that it has been a failure. There are excuses, of course. For some, including the awful Farage, the fault lies with how badly it was done. Meanwhile, among the population there is a growing understanding that they were conned, lied to, given false promises. They feel tricked into supporting an ideology that they do not share. Others expected all foreigners to be sent 'back home', which of course did not hapen. The xenophobes believed that it would put a stop to immigration, which of course it didn't.
If the same question was put in a referendum the answer would be a decisive 'No', if recent opinion polls are to be believed. (I was a Remainer and now I am a Returner.)
