Britzit-247

 was a British colony.

The inhabitants of the planet were extremely angry about something, so they decided to go to another world, which was built entirely on their mutual annoyance. Later, they forgot what they were annoyed about, but were annoyed anyway.

The last copy of John Jones' final album was located there, which was stolen by the Eleventh Doctor and Alice Obiefune. While examining the album, the Doctor accidentally broke it.

On Britzit-247, there was a river which resembled the Thames, except it was made of molten lava. There was also a building that looked like Big Ben. (COMIC: Remembrance)
