British Prime Minister Theresa May will seek to overturn all 15 Lords defeats on her flagship Brexit legislation in a single dramatic day next week, putting her authority on the line.
Relatively, MPs were warned that they will be voting into the early hours of Wednesday morning when the EU withdrawal bill finally returns to the Commons next Tuesday, after weeks of delay.
Key controversies including leaving the EU customs union and single market, the Irish border and parliament's power if the government's exit deal is rejected will all be up for grabs.
However, the decision to try to ram through 15 votes in a single sitting - on all the crucial Brexit issues - immediately drew fierce criticism from Labor.
The decision comes after many months in which the Commons considered little legislation, packing its schedule with vote-free debates instead.
Three days of scrutiny were expected on the Lords amendments, not a single 12-hour sitting - with an entire day for the customs union and single market.
The legislation was ripped apart during its 20-day passage through the Lords, where the 15 defeats also included reversals on the feared loss of environmental and human rights protections.
Meanwhile, May was under fierce pressure from Brexit-backing Tories to face down her pro-EU rebels and enforce her promises on the customs union and single market.
