Chris Mason, the top dog of the BBC’s political team, has said Labour has achieved a “spectacular victory”.

Their result after the last election was their worst since 1935 he explained, and they faced a mountain of a task to win even by a small margin.

But they’ve done it, and “Sir Keir Starmer will be prime minister by lunchtime, taking to Downing Street a colossal majority”, he says.

The big picture is this: within hours, we will soon have our fourth prime minister in under two years.

The whirlwind of British politics continues.

We live in a world of unprecedented voter volatility – more people in more places are more willing to change their minds more often and more quickly about politics than ever before.

And it has happened again.
