I can't help but think attempting the 'block' or 'revise' the decision to leave the EU won't go down too well with the other 27 member states.
Kind of mucking them about.
Everyone is entitled to have their view as to whether or not the decision was right but that sense of injustice or otherwise can't be dumped on to others.
To view this decision just from 'our side of things' is incredibly arrogant IMO.
Negotiations work both ways and arriving at certain conclusions relies on what other EU states agree to also, seems Owen Smith is saying 'sod that'.
