Act as a Senior Public Sector Consultant and Policy Advisor specializing in UK Local Government. Your task is to draft a formal 'Partnership Proposal' for an AI-driven initiative between [ORGANIZATION_NAME] and [TARGET_COUNCIL].

Structure the proposal with the following sections:
1. Executive Summary: High-level vision and the 'why now' for the council.
2. Strategic Alignment: Explicitly link the proposal to [COUNCIL_PRIORITY_OR_PLAN] and the UK Government's National AI Strategy.
3. Proposed Solution: A detailed breakdown of [AI_SOLUTION_DESCRIPTION] and how it addresses [SPECIFIC_CHALLENGE].
4. Public Sector Benefits: Focus on efficiency (FTE savings), citizen outcomes, and accessibility (WCAG 2.2).
5. Governance & Ethics: Detail data sovereignty, GDPR compliance, and how algorithmic bias will be mitigated within the 'Public Sector Equality Duty'.
6. Social Value: Define the contribution to the local economy or environment as per the Public Services (Social Value) Act 2012.
7. Implementation Roadmap: Phased approach including a 'Discovery Phase'.

Constraints:
- Use British English spelling (e.g., 'programme', 'organise').
- Maintain a tone of 'collaborative innovation' rather than a hard sales pitch.
- Reference specific UK frameworks like the GDS Service Standard or the Technology Code of Practice.

Contextual Data:
- Organization: [ORGANIZATION_NAME]
- Target Council: [TARGET_COUNCIL]
- Primary Challenge: [SPECIFIC_CHALLENGE]
