## Unreleased

## [1.22.0] - 2020-12-02

### Fixed

- Accessibility issue with hmrcHeader when displayHmrcBanner set to true. Previously this
component defined two top-level 'banner' landmarks failing accessibility tests. On advice from the
HMRC accessibility team, the HMRC banner has been moved inside HEADER so that screen-reader users read the
banner as part of the overall header and can skip to the main content more easily.

when the focus state is applied. This also benefits users who override
colours in their browser as they will still see the crown.
