MPs have clashed over Traditional Unionist Voice (TUV) leader Jim Allister's proposed law which seeks to overturn Northern Ireland's post-Brexit trading arrangements.
His private member bill aims to replace the Windsor Framework, which governs trade between Northern Ireland and Great Britain.
Allister described the deal between the last government and the European Union as an "undemocratic plundering of the Northern Ireland statute book".
The European Union (Withdrawal Arrangements) Bill was debated for nearly five hours on Friday in the House of Commons.
