Two explosive reports into alleged corruption at Unite the Union – Labour’s biggest donor – have been handed to the police today, after both probes found evidence of “eye-watering” overcharging on contracts and “potential criminality”. Their HQ was already raided by police earlier this year…

The investigations were conducted by a KC and an accounting firm respectively, with a source telling Sky News today:

“There was pricing and overcharging that would make your eyes bleed […] There are such discrepancies in the money that the police may want to take things further.”

Unite boss Sharon Graham has now insisted the reports won’t be published until the police probe is over, although given McClusky’s Birmingham hotel complex – the one that was supposed to cost £7 million – somehow ended up costing nearly £100 million, it’s not hard to imagine why the KC has a few questions.

Of course, it was only yesterday when Lisa Nandy had this to say on Times Radio about the unions filling Labour’s coffers:

“I would far rather be taking money from ordinary working people, whether it’s our paramedics, or our postal workers, or our ambulance workers to support the labour movement […] This is the cleanest money in British politics.“

24 hours is obviously a long time in politics. Guido feels Rayner would have already published a screeching letter were this about a major Tory donor…
