"Liz Truss even crashed the pork market,” Rayner added as she dramatically pointed her finger: “Now that. Is. A. Disgrace."
The joke prompted an eruption of laughter along with cheers and a long round of applause from the audience.
"Now you think that snouts in the trough was one of the things they could manage," Rayner added in another savage burn at her political rivals.
\u201c"Liz Truss has even crashed the pork market.

Rayner's mention of pork markets is a reference to Truss's famous meme that came from her speech at the 2014 Conservative Party Conference when she was the then secretary of state for environment, food and rural affairs.
"We import two-thirds of our cheese. That. Is. A. Disgrace," she said at the time.
“In December I’ll be in Beijing, opening up new pork markets.”
Truss then gave the audience a wide grin in anticipation of a round of applause which did come eventually... after an awkward moment of silence.
People on Twitter were absolutely living for the meme callback during Rayner's top-tier trolling.
