Yesterday came the news that everyone had been waiting for. Or at least, part of it. The police had issued 20 finesThis does not necessarily mean that 20 people were fined: some could have been fined more than once. to people who had broken lockdown rules by taking part in illegal gatherings at 10 Downing Street. The culprits were not named. All that was known was that they did not include Boris Johnson.

There is speculation that the police started with "low-hanging fruit" - easy cases, involving people who admitted to wrongdoing. Those who denied it - such as Johnson - could be dealt with at a later date.

The fines are deeply embarrassing for the prime minister. He was still refusing to admit that there had been illegal parties at Number 10, despite allegations that 12 had taken place. That refusal will infuriate people who made sacrifices to observe lockdown rules.

Commentators have been quick to compare Johnson to historical figures who showed contempt for ordinary people.

"At the heart of successful liberal democracies lies a remarkable collective leap of faith," writes William Davies, "that when public officials, reporters, experts and politicians share a piece of information, they are presumed to be doing so in an honest fashion". People trust them not to lie.

In recent years, Davies argues, this trust has been undermined. Revelations of MPs fiddling their expenses, US soldiers mistreating prisoners in Iraq and phone-hacking by News of the World reporters all feed into the narrative of misconduct.

This has been used by some to cast doubt on public figures in general. Politicians such as Donald Trump claim that the truth is being hidden from us by "elites" - including the media.

"Unless liberal institutions and their defenders are willing to reckon with their own inability to sustain trust... the present trends will only intensify," Davies warns. Leaders like Trump will take over the world.

But according to one expert, Professor Philip Cowley, "One of the greatest myths in British politics is this idea that MPs now are an out-of-touch elite." For him, they are probably more in touch with their constituents than ever before.

Yes: Nobody relies on politicians to tell the truth anymore. They are only out for themselves and say whatever people want to hear in order to stay in power. Boris Johnson has a reputation as a liar.

No: You cannot generalise about politicians any more than you can about other groups of people. Plenty of them are thoroughly honest. If they were all crooks, nobody would vote in elections at all.

Or... We are going through a bad phase at the moment, with a lot of disgraceful people in positions of power. But that does not mean that the next generation of politicians will be untrustworthy.
