Former Labour MP David Chaytor has been jailed for 18 months for making false Parliamentary expenses claims.
Chaytor, 61, became the first politician to be convicted and sentenced over the expenses scandal which has rocked Westminster.
He submitted bogus invoices to support claims totalling £22,650 for IT services and renting homes in London and his Bury North constituency.
But the properties were owned by him and his mother, and he did not pay out any of his own money, Southwark Crown Court in London heard.
Chaytor, of Lumbutts, Todmorden, West Yorkshire, pleaded guilty last month to three counts of false accounting between November 2005 and January 2008.
