In April 2019, a report commissioned by the German Greens concluded that the backstop could allow the UK to undermine EU standards on the environment, consumption and work due to a lack of sufficiently detailed controls.  When the insurer takes possession of shares, as stated in the agreement, the shares are owned by the organization that manages them as it sees fit. Shares are treated like any other investment acquired by normal market activity. The issuing company cannot impose restrictions on the trading of shares. The technical insurance agency may hold or sell the associated securities in accordance with the rules governing the entire business. The completion of the European Single Market in 1992 (initiated by Commissioner Lord Cockfield) and the Good Friday Agreement (negotiated by US Senator Mitchell) in 1998 were considered possible to dismantle the important border infrastructure between Northern Ireland and the Republic of Ireland.  They believe that the UK could end up in an “open” customs union with the EU, despite the assurance that the backstop is designed as a temporary situation. Many Conservatives and DUP members supporting Brexit continued to oppose the no-deadline backstop, fearing it would indefinitely link the UK to many EU rules, although the DUP said in January 2019 that it was open to the idea of a temporary backstop.  The EU (particularly the Irish Government) considers that a time-limited guarantee has no value, not least because of scepticism about the short-term provision of “alternative agreements”.  Where are the EU and the UK in the backstop issue? British Prime Minister Boris Johnson has made the exit of the backstop a red line for Brexit negotiations. Under the agreement negotiated by Theresa May, after the official exit from the EU, the UK would enter a transition period during which it would remain a member of the body`s economic zones, namely the internal market and customs union. On 17 October 2019, it was announced that UK and EU negotiators had reached a “new” or “revised” agreement on the Irish border, which put an end to The Irish backstop proposal.

Under the “backstop” the whole of the UK would enter a “single customs territory” with the EU. There are many, but, for the most part, there would be no tariffs on trade in goods between the UK and the EU and some trade restrictions would be lifted (although not all of them). Boris Johnson opposed the backstop and said it was undemocratic and could trap the UK in EU customs territory. Parliament voted for the first time against the withdrawal agreement in January 2019. The aim is to keep the UK in a form of customs union with the EU if no trade agreement is reached. Both the EU and the UK said they did not want the backstop to be used, but this was not safe enough for some MEPs, who felt that the backstop could mean that the UK would remain closely linked to the EU indefinitely.
