Pelosi warns changes to Northern Ireland protocol could affect US trade deal with Britain

Bluntly worded intervention comes as tensions rise over plans by Liz Truss to nullify parts of the protocol

The US House Speaker, Nancy Pelosi, has warned that unilateral UK legislation affecting the Northern Ireland protocol could endanger British prospects for a free trade deal with the US.

Pelosi's bluntly worded intervention came two days after the UK foreign secretary, Liz Truss, confirmed that the government was planning to table legislation that would nullify parts of the protocol by exempting some goods moving between Great Britain and Ireland from EU customs checks.
