Act as a Senior Client Relationship Manager with expertise in the [UK_SERVICE_SECTOR]. Your goal is to design a comprehensive relationship management strategy for a client named [CLIENT_NAME/TYPE]. 

Context:
- Our Service: [SERVICE_OFFERED]
- Current Relationship Stage: [RELATIONSHIP_STAGE]
- Key Goal: [COMMUNICATION_GOAL]
- Tone Preference: [TONE_STYLE]

Please provide the following:
1. RELATIONSHIP AUDIT: Analyze the current stage and identify potential friction points specific to the UK market (e.g., British 'polite indirectness' or over-promising).
2. COMMUNICATION PLAN: Draft a 3-part sequence (Initial Outreach, Value-Add Check-in, and Long-term Retention message). Ensure the language uses British English spelling and professional norms.
3. VALUE-ADD IDEAS: Suggest 3 specific ways to add value to this client outside of the core service (e.g., industry insights, networking intros, or UK-specific regulatory updates).
4. OBSTACLE HANDLING: Provide a script for handling a common difficult conversation (e.g., price increases or project delays) using a 'partnership-first' approach.

Constraint: Avoid overly aggressive 'American-style' sales tactics. Focus on reliability, understated competence, and long-term mutual benefit.
