It seems the UK government is still very much talking the talk that they believe we (the UK) will be part of the UPC  system after Brexit. How this is possible is yet to be negotiated but, as Daniel Alexander QC said earlier in the discussions before the House of Lords’ EU Justice Sub-Committee, “where there’s will there’s a way”.

For now I guess it’s just one of a multitude of matters still to be negotiated - but it seems there is still the will at least.
