## Question put to the AI subject

Has the FCA withdrawn pre-Consumer Duty Dear CEO letters following implementation, and if so how many were removed and under what document?

## AI subject's verbatim answer

I cannot provide a verified specific number of withdrawn letters from the available search results... the search results do not identify a definitive public list of how many specific pre-Consumer Duty Dear CEO letters have been formally withdrawn

## Verbatim regulator text contradicting the answer

> FS25/2 (March 2025): FCA removed more than 90 pre-Consumer Duty Dear CEO letters and cleared over 100 old multi-firm reports. Harmonising definitions of 'retail customer' and 'SME' across Handbook.

_Section anchor:_ FS25/2 (March 2025) — Rules and Dear CEO letters withdrawn post-Consumer Duty

## Failure mode

**`inference_drift`** — Inference drift — the AI inferred a conclusion the regulator's text does not warrant, often by combining unrelated provisions.

## Citation-issue types

- **Pretextual** — <https://www.fca.org.uk/news/news-stories/next-steps-consumer-duty-rule-review>
