There has been a new deal agreed on by the UK and the EU. As noted above, one of the main challenged faced by ex-PM Theresa May was how to resolve the Irish backstop problem (see above). The agreed new deal, however, has sought to resolve this issue. Specifics on what has been proposed can be read in this summary written by the BBC. The deal, however, has not addressed other prominent issues, such as the transition period and future relationship between the UK and the EU, that have also challenged May.
