Candidates contesting tomorrow's city council election say the Sauchiehall Street centre has been closed to the public for years and is now in need of urgent repair.
Green councillor Nina Baker is demanding council arms' length company City Property explains what she describes as its failure to manage the gallery properly.
She said: "The Sauchiehall Street entrance to the Galleries is looking very shabby.
"I have been told that because Glasgow Life don't want it, the city shouldn't let it out to any competing gallery use either.
"I think that is a nonsense."
