Police are to investigate bombshell claims that officials of the Scottish National Party accepted envelopes stuffed with cash from a relative of one of the party's MPs.
Allegations made by a whistleblower state that senior party figures received tens of thousands of pounds from a Scottish businessman related to a prominent nationalist politician – and that they broke electoral law by failing to publish details of the gifts.
The letter identifies the businessman, and the SNP MP to whom he is related. It also names party figures said to have either received or been aware of the donations.
