ADDITIONAL INFORMATION

I was able to work around this by pinning the ubuntu versions e.g.:

Package: mysql-client-core-8.0
Pin: origin "gb.archive.ubuntu.com"
Pin-Priority: 700

Package: mysql-server-core-8.0
Pin: origin "gb.archive.ubuntu.com"
Pin-Priority: 700

(in my case apt policy showed origin as gb.archive.ubuntu.com)
