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 a hundred 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.
