Jenny Chapman, who was sacked as Labour leaders chief adviser, has been given a new role in the Shadow cabinet. Jenny will now go head to head with Lord Frost as Labours Brexit Adviser.
Ms Thornberry attempted to act tough on Twitter, saying Baroness Chapman would “be taking no prisoners”.
Thornberry wrote: “I’m looking forward to working closely with @JennyChapman to ensure we protect our trade with Europe – our biggest and most important market.”
“Watch out, Lord Frost, she’ll be taking no prisoners!”
