Lazy and fraudulent: we saw the true Johnson at the Covid inquiry – and why his like must never have power again | Martin Kettle

He confirmed himself as manifestly unfit. Those who gave Britain such a leader should carry the shame of it to their graves

Francois Mitterrand once said that the most essential single attribute for success in politics is indifference. France's former socialist president possessed that quality to his core. His views could turn on a centime, from right to left to centre and back again, as the political situation and his own power required. Indifference, skilfully translated into policy and action, was an essential driver of his 14-year presidency.

Boris Johnson is blessed - which may not be the right word - with an indifference of his own. Johnson is lightly encumbered with political principles, since he believes in little except himself. He famously wobbled about which side to take on Brexit. His instinctive capacity for indifference took him right to the top of the greasy pole. If that is his blessing, his curse is that, unlike Mitterrand, he could not then turn it into effective government action.
