The closing policy aside warns against reading British defence plans as fixed commitments. Decisions scheduled beyond the next general election will belong to a future parliament and its government. A new prime minister, defence minister, or strategic defence review can change priorities before distant retirement and procurement dates arrive. One parliament cannot bind the decisions of its successors, which limits the force of promises that extend beyond the current government's term. Prolonged continuity of government and prime minister offers one way for distant commitments to survive, with Margaret Thatcher and Tony Blair cited as examples of long premierships. Frequent changes of prime minister make that continuity harder to sustain. This limits confidence in retirement and procurement promises extending far beyond the current government's term.
