His Parliamentary log-in id would be ‘carberryj’ as a result [see the “alias” entry above], and the way that computers are set up in the Commons, the default ‘author’ of any Word documents [used to create the document before it was PDFed]would correspondingly be ‘carberryj’. This raises the question – has Peter Hain been using House of Commons facilities (funded by the taxpayer) to further his leadership bid ?
He’s not been allowed to use Ministerial facilities (see PQ below) – and he hasn’t yet opened a campaign office (as you will recall, during the 2005 Conservative Party leadership race, the various teams set up campaign offices outside Parliament).

Mr. Heald: To ask the Secretary of State for Northern Ireland what guidance he has issued to his special advisers concerning alterations to their duties during the campaign for the deputy leadership of the Labour party. 
Mr. Hain: Special advisers act in accordance with the requirements of the “Code of Conduct for Special Advisers”. This makes clear that special advisers may assist with a leadership or deputy leadership campaign, but it must be in their own time. In addition, the Cabinet Secretary has issued guidance to Departments on conduct in the run-up to such elections. A copy has been placed in the Library for the reference of Members.
So that's clear then.
