The most recent Brexit deal negotiated with the E.U. must be approved by the British parliament to avoid yet another round of deliberations with the E.U. delegates.

Jeremy Corbin, leader of the Labor party, made the following statement while speaking with the BBC.

“We are the opposition party, our job is to challenge the government.” Corbin said.

The current British government is headed by Theresa May, the leader of the Conservative party, is pushing for a strong Brexit. Corbin, on the other hand, argues for no Brexit. As previously mentioned Corbin will push back against May unless there is a middle ground that pleases both parties.

According to The Guardian, for the Labor party to accept the Brexit it would have to pass their six tests:

• Guarantee strong and collaborative relations with the E.U.
• Same benefits of the single market and customs union
• Fair management of migration for the economy and different communities
• Defend rights, protections, and from a race to the bottom
• Defend national security and help tackle cross border crime
• Help all regions and nations of the U.K.

The second test on the list is a key one. While in the E.U., Britain still has to conform with the E.U.’s policy on materials in products, but they have easier trading processes within the union. But, once they leave they still must conform while selling in European Union states and losing those easier processes. The Labor Party wants those processes to stay how they are, for the benefit of the workers in the U.K..

As of late September, the most recent negotiations have not reached a deal that pass the six tests. Due to it not meeting the conditions, it is unlikely that the members of parliament will approve of the current Brexit deal, which leaves the negotiations back where they started.

This process is not likely to be over any time soon, and with the deadline of the Mar. 29 2019, the negotiations are going to take a long time, seeing as in the past few years only two deals have been reached.
