If it appears to Her Majesty that the privileges and immunities accorded to a mission of Her Majesty in the territory of any State, or to persons connected with that mission, are less than those conferred by this Act on the mission of that State or on persons connected with that mission, Her Majesty may by an Order in Council withdraw such of the privileges and immunities so conferred from the mission of that State or from such persons connected with it as appears to Her Majesty to be proper.

An Order in Council under this section shall be disregarded for the purposes of section 50(4) of the British Nationality Act 1981 (circumstances in which certain persons entitled to exemption under section 8(3) of the M1Immigration Act 1971 are to be regarded for the purposes of section 1(1) of the said Act of 1981 as settled in the United Kingdom).
