UK (re)joins the GPA
The GPA members and the UK have reached an agreement allowing for the country to acceed to the Agreement if and when it leaves the European Union. This agreement ensures a continuity of the international procurement legal regime for UK-based undertakings and those based on the GPA members.
Back in 2017 myself and Albert Sanchez-Graells concluded that the UK was not a party to the current GPA in its own right and would have instead to apply for accession. Our colleague Ping Wang from Nottingham reached a similar conclusion.
In the paper we posited that the accession could follow a streamlined process but we assumed that even then it would take a significant amount of time. In this instance we were proved wrong, with the accession ocurring quicker than we anticipated.
Regarding possible change to the UK's legal regime(s) post-Brexit, we remain convinced that the accession to the GPA limits the scope of the changes that can be introduced.
