Leslie Ash (born 19 February 1960) is a British actress best known for playing Deborah in the sitcom Men Behaving Badly. She started out as a model and is sister of Hot Gossip dancer Debbie Ash . She attended the Italia Conti stage school and recently has taken several "serious" dramatic roles.

She is married to former footballer Lee Chapman . It has often been claimed in the tabloid press that he physically abuses her on a regular basis. Such reports are lent some credibility by the apparently frequent visits to hospital Ash has made. Chapman was once photographed leaving a Marbella Night Club with a young model, and is rumoured to have entertained several torrid love affairs. Ash was also featured in the press when overly-succesul collagen injections to increase the size of her lips left her with what the tabloid press described as "trout pout".

In June 2004, it was announced that an MSSA infection may have rendered her permanently unable to walk. She contracted the infection while recovering from a rib injury, which was reported to have been sustained in sex with her husband. In late August Ash was seen taking some steps with the assistance of crutches.

Ash now calls for cleaner hospitals as a result of her experiences and regularly addresses audiences of healthcare officials on the subject.
