Yes, says the EAT in Onyango v Berkeley Solicitors.
Dealing with a novel point, the EAT held that the statutory wording (s47B ERA) did not limit the whistleblower's protection to disclosures made during the relevant employment.

The case was remitted for determination of the issue to a different tribunal.
