They could do a real brexit tour
.. as the article said, London not representative of pro brexit
They could nip around a few pro brexit areas of the country, even grabbing a few scenic seaside places, visiting pro Brexit areas such as Sunderland, parts of Cornwall , Wales etc.
The LSE guide could have great fun explaining why areas that benefit from lots of EU funding voted to leave the EU, and could then discuss how remote the possibility of a Mayhem government providing additional funding those areas to anything like the degree they benefited from the EU.
Or they could just use census data and do England only, pick English areas with a big majority of white "natives" and older demographic, chances are they were heavily brexit ()
