## In brief

- Microsoft will enable Anthropic's Claude models by default for UK Copilot tenants starting December 9.
- UK tenant administrators have until then to decide whether US-based processing fits their compliance requirements.

## Why it matters

Claude processing is US-based, so UK organisations with data residency or compliance obligations may need to act before the default takes effect.

## What to do

- Decide before December 9 whether US-based processing of Claude models fits your compliance requirements.
