The Foyle MP said that the bill is a bad faith breach of the Britain’s obligations under international law that has seriously damaged trust between parties in negotiations.
Said Mr Eastwood: “The European Commission’s decision to begin infringement proceedings against the British Government should come as no surprise to anyone.
“The terms of the UK Internal Market Bill represent a clear breach of international law obligations under the Withdrawal Agreement and this step is the logical outworking.
“The British Government’s position is a bad faith breach of responsibilities entered into by Boris Johnson a year ago.
“The Northern Ireland Assembly has already rejected the argument that this legislation protects peace and mandates our First Ministers to oppose the bill.
“Boris Johnson should withdraw the bill and return to negotiating in good faith with the EU.”
