2014 JHA Opt-out Decision

I thank my right hon. Friend, who is being very generous. I welcome her words about the importance of this House maintaining control over these matters, but we lose control over them in perpetuity if we opt back into any of the measures. That therefore represents a permanent transfer of sovereignty that the current situation does not represent. Do I take it from her comments on the renegotiation that what the coalition agrees to opt back into would not be subject to renegotiation by a future Conservative Government? It would seem rather incredible to believe that a British Prime Minister could opt into something in one Parliament and then in the next Parliament go back and say, “No, we want to opt out again after all.”
