UK MPs will vote on Thursday on delaying Brexit after they decisively rejected a no-deal Brexit.
Prime Minister Theresa May says she favours requesting a short extension to the process if her Brexit deal can be agreed by the House of Commons in the coming days.
But she warns a long delay to Article 50 will be necessary if no deal's reached over the next week.
Britain's due to leave the EU on March 29.
Chancellor Philip Hammond says May's deal remains the best on the table:

Quakes rock Venezuela, killing at least 32 and injuring hundreds
Trump asks Congress for more funds to fight Iran, defying rebuke on war powers
Magnitude 6.9 quake strikes Japan's northeast, no tsunami warning
US, Iran at odds on nuclear inspections, frozen assets in deal to end war
Oman establishes temporary shipping corridor through Strait of Hormuz
