Sheelagh Nolan, the wife of former Nova Scotia Liberal leader Danny Graham, has lost her battle to cancer.
Nolan, 44, died Monday afternoon.
She was diagnosed with thyroid cancer soon after Graham won the leadership in April 2002. He stepped down as party leader in January 2004 after her condition worsened.
Nolan and Graham have three sons.
Premier Rodney MacDonald has extended his condolences to Graham, sons Patrick, Andrew and Colin, and Nolan's relatives.
A funeral is planned for Friday.
