Someone has stolen Leicester MP Liz Kendall's lunch. And they are prepared to do it again.
On Wednesday the covert politican spotting Twitter account @eyespyMP snapped a picture of a House of Commons fridge with a note attached signed by Kendall.
"Someone has stolen my lunch from this fridge," it said. "I do not appreciate this and warn other people - don't leave anything in here unless you're happy for it to go missing."
The culprit, possibly another MP, then replied with a yellow post-it note: "I took it... AND I'D DO IT AGAN."
Later on in the day another note was stuck to the fridge in response: "You are a very sick individual". However Kendall has denied that she was the author of the third message.
She tweeted: "I'm too busy campaigning to speculate on the identity of the Westminster tuna salad thief. But from now on I'll be eating a bigger breakfast."
