§ Mrs. Roche
Participation by the United Kingdom in the Schengen Information System (SIS) will require the exercise of the United Kingdom's opt-in under Article 4 of the Protocol integrating the Schengen acquis into the framework of the European Union, annexed to the Treaty of Amsterdam. The Government have submitted a request under this provision for participation in aspects of the Schengen acquis, including the SIS, and we are currently awaiting its approval. The SIS has been allocated to a legal base in the Treaty on European Union.
