Tamworth

 was Minister for the Air at the time of the launch of the R101. He had improvements made to the airship so that he could return the Triskele Engineer-Prime back to her people. On discovering the Eighth Doctor and Charlotte Pollard, he thought that they were German spies for the Hindenburg corporation.

After Rathbone killed the Triskele Lawgiver, Tamworth elected to stay behind and become the new Lawgiver to stop the Uncreators destroying the Engineers. (AUDIO: Storm Warning)
