Not Legal to do,
some have stated.
[DUP minister Edwin Poots has ordered
his officials to halt Irish Sea border
checks from midnight.
He had been threatening to act,
as part of the DUP's ongoing opposition
to the Northern Ireland Protocol.
Mr Poots said he had taken legal advice
which meant he could direct the checks
to stop in the absence of executive approval for them.
The protocol was agreed by the UK and EU
to ensure free movement of trade across
the Irish border after Brexit.]
