Glasgow, Caledonia Prime

Glasgow was a location on Caledonia Prime. In 200,000, on the day Cathica Santini Khadeni destroyed the Jagrafess and started the 100 years of hell on Earth, water riots in Glasgow entered their third day. (DW: The Long Game, Bad Wolf)

Behind the scenes
The fact that the story is not referring to Glasgow, Scotland is not made through dialogue, but through graphics. A video terminal behind Cathica while she's talking about the water riots in Glasgow, clearly say those riots are on Caledonia Prime.
