UK opposition parties have issued a joint statement saying that they agreed to prevent a no-deal Brexit.
"The attendees agreed on the urgency to act together to find practical ways to prevent No Deal, including the possibility of passing legislation and a vote of no-confidence", the statement said.
The talks were hosted by Labour leader Jeremy Corbyn, with the participation of the Scottish National Party, the Liberal Democrats, the Green Part,y and the Independent Group for Change.
Next week, the British Parliament returns from its summer break and is preparing for debates with Prime Minister Boris Johnson who promised to withdraw from the EU with or without the Brexit agreement.
The United Kingdom was initially supposed to leave the European Union on 29 March, but the UK Parliament’s failure to approve then-Prime Minister Theresa May's deal resulted in the deadline being moved to 31 October.
One of the main obstacles in EU-UK Brexit talks has been the Irish backstop, a solution that entails keeping Northern Ireland in the EU Customs Union, which is now being abolished by newly appointed Prime Minister Boris Johnson.
