Another week, another outspoken attack from Boris Johnson.
This week, it's "blasted" House of Lords reform.
London's mayor claims the 'Senate' plans will encourage "people who have never made it into Parliament; people who have been flung out of Parliament; has-beens; never-wozzers and people who can see the opportunity to avenge their rejections by finding an alternative route to power".
He lays the responsibility for the "completely unnecessary" reforms that make his "blood run cold" at the Lib Dems' door.
"This plan is a bunch of tidy-minded Lib Dem nonsense," he proclaims in the Telegraph.
"Clegg's scheme needs to be liquidated, vaporised and generally terminated with extreme prejudice."
Separately in the article, he voices support for Michael Gove's "brilliant" O-Level proposals and dismisses Ed Miliband's speech on immigration as "hopeless and intellectually dishonest" .
It's all thoroughly enjoyable, unless you're David Cameron, Lord Strathclyde or Nick Clegg, I expect.
