The amendment, tabled by SDLP Leader Colum Eastwood and South Belfast MP Claire Hanna, cites the impact of the legislation on devolution, the Good Friday Agreement and as a breach of international law.
Said the Foyle MP: “The Internal Market Bill represents the worst impulses of this British Government to attempt to trample the interests and rights of people in the North of Ireland.
“The SDLP, along with progressive opposition parties at Westminster, is totally opposed to the legislation which brings us closer to a hard border in Ireland than we have been at any point in these negotiations.
“US congressional leaders have already spelled out what that means for any hope of a trade deal with Britain.
“We will continue to use our influence with the United States to secure an outcome the protects the progress made in Ireland over a generation.
“SDLP MPs have tabled a reasoned amendment to the bill, outlining our serious concerns about the intentional breach of international law and the overreach into the authority of the devolved institutions.
“This administration has demonstrated time and time again that it doesn’t care about the interests of people, businesses or communities on the island of Ireland.
“Their only motivation is narrow political advantage.
“The SDLP will continue to take a stand for people in the North of Ireland and we’ll resist this legislation at every stage.”
