The year's first Christmas special arrives tonight as The Madame Blanc Mysteries begins its fifth series on Channel 5 at 9.05pm. In the cosy crime drama, the mayor of Sainte-Victoire is murdered and her body is dumped in the village fountain, disrupting antique-dealing sleuth Jean's Christmas Eve wedding plans. Sally Lindsay plays Jean, who joins the investigation and suspects a different motive even though a local builder is under suspicion.

Documentary and finance show

At 7pm on BBC Two, health correspondent Sharon Barbour presents a one-off documentary about women in County Durham whose mastectomies were found to have been unnecessary. One woman says, "I feel as if I've been butchered," and a former consultant surgeon calls what happened a "horrific outlier."

On ITV1 at 7.15pm, home-finance guru Martin Lewis tackles the Budget, with viewers relying on him for help with the choices they face.
