A Sky News investigation has discovered Northern Research Group (NRG) MPs acquired political donations from a non-public donor to assist them with campaigning - weeks after they authorised 1000's of kilos of taxpayer funded bills to be spent on the NRG.

It raises questions on whether or not MPs authorised public funding to be spent on the NRG as a result of they knew they'd be rewarded with a marketing campaign donation. As a results of the investigation, the parliamentary bills watchdog IPSA has introduced an investigation.
