In her statement to Parliament, Theresa May stated that the EU wanted a backstop to the backstop. What does she mean by that?
If I understand correctly, the backstop is a fallback position for customs and regulatory arrangements in Northern Ireland, if the UK/EU negotiations fail to reach agreement during the transition phase defined in the Withdrawal Agreement.
With this primary backstop in place, can the UK continue to unilaterally decide the future for Northern Ireland if talks break down during the transition period?
