Hi @bradmorton1, please would you be able to add an entry to the change log (date field can be today) and bump the version in package.json and package-lock.json to 1.1.3?

I’ll get this into the develop environment today.

I think there could be a future risk with breaking changes with the cookie script not being versioned on assets.nhs.uk - may consider self hosting the JavaScript.

Looks good - do you know if this cookie consent release includes the fix for the success banner link hover colour that was done a while ago?

If so I'm going to remove this hotfix styling: https://github.com/nhsx/nhsx-website/blob/develop/app/styles/nhsx/_utilities.scss#L66
