Article 4

The Greater London Council shall make to the county council of Essex, Hertfordshire, Kent or Surrey, in respect of the relevant liabilities in relation to the county fund of such council, otherwise than in respect of fire services, such payments as may be agreed by the councils concerned, or in default of agreement determined by an arbitrator agreed upon by such councils, or in the absence of agreement appointed by the Minister, to be proper by reason of the inclusion of part of the county in Greater London.

Any agreement made under the preceding paragraph may be varied from time to time, in particular on any extension of the Pensions (Increase) Acts 1920 to 1965, by agreement between the councils concerned.
