Margaret Moran, the former Labour MP who claimed for dry rot treatment on a home more than 100 miles from her constituency is to be charged with fiddling her expenses by more than £60,000.
Miss Moran, one of the last politicians investigated over the MPs' expenses scandal, will appear before magistrates facing 21 charges relating to her parliamentary claims.
The former MP for Luton South, will appear before City of Westminster Magistrates' Court on September 19, the Crown Prosecution Service said.
The Director of Public Prosecutions said there were no more parliamentary expenses fraud cases awaiting review.
Keir Starmer QC said "there is sufficient evidence and it is in the public interest" to bring criminal charges against Moran.
Miss Moran, who has been suspended by her party, claimed more than £20,000 for the treatment of dry rot at her Southampton home.
