'Symbols do matter'published at 14:01 Greenwich Mean Time 29 January 2020
Mr Greer says: "Symbols do matter."
The decision to continue flying this flag matters a great deal to many of the EU citizens living in Scotland, he argues.
He insists the Tories are delighted this debate is taking place as they think they will benefit politically with those who want the flag to come down.
The only real losers are the Lib Dems who want to remain in Europe but will shortly vote with the Tories to bring the European flag down, he says.
The Greens will cast their vote to keep the European flag flying over this parliament, he tells the chamber.
