Thank you for your request regarding regional voting patterns/preferences in elections and referendums in Britain.
We are unable to provide any statistics on regional voting patterns as we do not hold data about how people vote.
The Electoral Commission website contains information about the results of elections so they may be able to answer your question.
Please do not hesitate to contact us directly on pop.info@ons.gov.uk, if you require anything further.
