Say I am arrested tomorrow for a serious criminal offense which I did not commit. It would be a complete surprise to me, and being an ordinary person I don't have any relationships or knowledge of good/affordable criminal defence solicitors.
I understand I could ask for the duty solicitor, but I don't trust them, or think they won't represent me as well as a paid solicitor.
I understand I can ask to call my own solicitor. Do I need to already have a relationship with this solicitor, or have their number to hand or will the police provide some resources/time to research a solicitor?
Asking particularly for the UK but would be interested in other countries if this varies.
