Disgraced Labour MP Denis MacShane admitted to using a fake name to fraudulently claim expenses for trips to Europe, it emerged.
Allegations were made against MacShane as far back as 2009.
However, he confessed to submitting invoices signed with what he called a "nom de plume" in a 2010 letter to the Parliamentary commissioner.
The former Labour MP repeatedly put in receipts from the “European Policy Institute”, a group he subsequently described as a “loose network” with “no office, no staff, and just a post-box address.”
He used a name on the receipts which he explained was “a nom de plume used over the years to cover expense claims and payments from the EPI.”
