Chris Mason: The ghost of Boris Johnson haunts Rishi Sunak

Chaos, uncorked. Again.
In his seven months as prime minister, the most notable characteristic Rishi Sunak has brought to government is - relatively speaking at least - stability.
But 2022 - or much of it - was defined, politically, by a soap opera of Conservative squabbling.
It didn't disappear with the arrival of Mr Sunak in Number 10, but it quietened down substantially.
Now, it is back again.
Downing Street was an observer of events on Friday - it only found out about Boris Johnson's resignation as an MP when the rest of us did.
A former prime minister, in Boris Johnson, with a life-long knack for throwing stones and grabbing attention, doing just that.
A current prime minister, in Rishi Sunak, languishing in the opinion polls and now confronting two appointments with a disgruntled electorate, courtesy of two people meant to be on his own side.
