From October 2016 at Guido Fawkes https://order-order.com/2016/10/25/labour-given-maximum-fine-expenses-fraud-mcnicol-committed-offence/
'Labour has been hit with the maximum £20,000 fine after the Electoral Commission found a total of 107 invoices were missing from the party's general election expenses return. Labour general secretary Iain McNicol was found to have committed an offence under section 82(4)(b) of PPERA in respect of the missing payments and a further offence under section 82(4)(b) in respect of the missing invoices. Labour have also been slammed for failing to declare payments in relation to their Labour Express and Labour Students bus tours, which were revealed by Guido.'
The BBC will do their best not to refer to this in their coverage of the Conservative Party fine.
