The peer was a front bench spokesman for the Conservatives in the House of Lords Former Tory peer and Essex Council leader Lord Hanningfield has been jailed for nine months for fiddling his parliamentary expenses.
Paul White, 70, was convicted of six counts of false accounting relating to nearly £14,000 of claims in May.
White has said he will seek leave to appeal against the verdict. If granted, the Court of Appeal will hear the case.
He was found guilty of claiming money for overnight stays in London when he had actually returned home to Essex.
Peers were able to claim up to £174-a-night when attending Parliament, if their main home was outside the city.
But during his trial in May, the court was told White submitted false claims for hotel bills including one when he was actually on board a flight to India at the time.
He also fraudulently claimed for train fares and car mileage.
White is the sixth parliamentarian to be jailed for expenses fraud. Tory peer Lord Taylor and four former Labour MPs – Eric Illsley, David Chaytor, Jim Devine and Elliot Morley – were all given prison sentences.
Chaytor and Illsley have since been released under the home detention curfew scheme.
The BBC’s Helen Fawkes, at Maidstone Crown Court, said the judge took into account White’s reportedly fragile mental state and his age before sentencing him. She said the judge was told that the former peer had expressed suicidal ideas at the prospect of being sent to prison.
