Theresa May's no-deal Brexit preparations suffered a blow after MPs defeated the UK Government in the Commons.
Labour former minister Yvette Cooper tabled an amendment to the Budget-enacting Finance (No. 3) Bill which attracted support from Tory rebels.
Her proposal aims to restrict the Government's freedom to use the Bill to make tax changes linked to a no-deal Brexit without the "explicit consent" of Parliament.
It was supported by 303 votes to 296, a majority of seven.
