I wrote an email to some local councillors about a planning issue that is high profile and controversial. I have a connection to the organisation that is making the application. The email contained my personal address and email address.
A few hours later, a different local councillor (who has strong views on the issue) wrote a disparaging comment on Twitter, which made clear he had seen the email.
Is it not contrary to GDPR for councillors to share residents' correspondence without permission?
