Straight from an email from Your Party via their usual channel

"This morning, an unauthorised email was sent to all yourparty.uk supporters with details of a supposed membership portal hosted in a new domain name. Legal advice is being taken. That email should be ignored by all supporters. If any direct debits have been set up, they should be immediately cancelled. "

I believe this relates to the URL https://www.yourparty-membership.uk/

Please note yourparty.uk does not currently contain a link to the above domain.
