THE son of former Liberal leader Lord Steel is “devastated” by the death of a Haddington woman who fell unwell at a party in his home.

Claire MacCabe, 44, died in hospital after taking ill at a property in the village of Stow in the Scottish Borders on Saturday.

Police said the death was being treated as unexplained but not suspicious.

Ms MacCabe reportedly fell ill during a 52nd birthday party for friend Graeme Steel, son of the former politician David Steel.

In a statement, Graeme Steel said: “The tragic death of Claire MacCabe has left me, my family and friends devastated.

"Matt has lost his wife and their child has lost their mother; words cannot express how we all feel by this loss.”

A Police Scotland spokeswoman said: “Police in the Scottish Borders are investigating after a 44-year-old woman took unwell at an address in Stow during the evening of Saturday before passing away at the Royal Infirmary of Edinburgh later that night.

“The death is currently being treated as unexplained, but not suspicious, and inquiries are continuing.”
