@Walter Hinteler,
In an extraordinary Saturday sitting, the first since 1982, parliament will vote on approving Johnson’s deal.
The only topic will be "Brexit".
If the new Brexit deal is approved, Johnson can proceed with his plan to leave the EU on Oct. 31.
If rejected, he may seek approval to leave the EU without a deal on Oct. 31.
As far as it's known by now, the Democratic Unionist Party said it could not and will not support the deal.
The opposition Labour Party, the Scottish National Party and the Liberal Democrats have all said they will oppose it.
If JOHNSON loses votes on both a deal and no deal, he is required by law to write a letter to the EU requesting more negotiating time, delaying Brexit until Jan. 31 2020.
The government has said that it will both comply with this law and that Britain will leave the EU on Oct. 31 whatever happens.
Johnson has not explained how he plans to take these two apparently contradictory steps.
