Indirectly London Liverpool Street station is named after a person. The station is named after Liverpool Street right next to it. However, Liverpool Street is not named after the place it leads to (unlike for instance Oxford Street or Edgware Road), if anything Liverpool Street points towards Dover instead of Liverpool.
Liverpool Street is named after former Prime Minister Robert Jenkinson, 2nd Earl of Liverpool. Indirectly Liverpool Street station is therefore named after a former PM.
