If the Labour leadership contest wasn’t already a spiralling descent into insanity, Diane Abbott has now accused Harriet Harman of “voicing a Tory agenda“:

The increasing use of the “Tory” smear is becoming a hysterical, McCluskeyite witch hunt, rooting out any sign of moderation among the leadership candidates. The language and rhetoric of the Unite-Zombie-Socialist tendency is becoming prevalent… 

Yvette used it in a barely disguised attack on Kendall:

“I will set out ideas for the future that don’t just involve swallowing the Tory manifesto and set out a Labour vision for the future.”

Then Burnham used the same line in a direct slap at Liz:

“This doesn’t mean copying the Tories. Labour wins when we are better than they are.”

It’s clearly cutting through to the Labour grassroots, providing Kendall’s tensest moment at this morning’s hustings:

Her comeback was a zinger:

“If you believe that a strong economy, sound public finances and backing businesses are simply Tory values, the Tories will be in power for ever.”

The blue menace is real, report all suspected Tory activity…
