Mr. Maurice Quinn:

Let us consider the position of a member of the Defences Forces who is not in receipt of the Border duty allowance - they account for the vast majority - if he or she is rostered for security duty at the weekend, to protect the Central Bank or whatever else, he or she will receive a security duty allowance, which is a 24-hour payment. Staff in receipt of the Border duty allowance also engage in security duties, but they do not receive other payments; therefore, one is offset against the others.
