Blair feels another hand of history?

Tony Blair may have made some history he rather wouldn’t have. He may be the first serving Prime Minister to be questioned in an ongoing criminal investigation. The interview wasn’t under caution.Interestingly the official spokesperson drew an interesting distinction about the ‘type’ of peerages the investigation relates to:

“The prime minister explained why he nominated each of the individuals and he did so as party leader in respect of the peerages reserved for party supporters as other party leaders do. The honours were not, therefore, for public service but expressly party peerages given for party service. In these circumstances that fact that they had supported the party financially could not conceivably be a barrier to their nomination,”

Could loaning or donating money to a party not be considered “party service”? Guido classifies it as an explanation not a legal defence.
