in an information and communication service market or market segment. (3) Following the grant of the appropriate licences, every public operator shall, before the commercial launch of the relevant information and communication service, disclose to the Authority the relevant market or market segment in which it intends to operate. (4) The Authority may, after consultation with the Competition Commission, issue such guidelines as are necessary for the purposes of determining which public operator has significant market power in an information and communication service market or market segment. (5) Where a public operator has significant market power in a market or market segment, it may also be considered to have a significant market power in a closely related market or market segment, where the links between the two markets or market segments are such as to allow the market power held in one market or market segment to be leveraged into the other market or market segment, thereby strengthening the market power of the public operator. (6) Where a public operator has significant market power in a market or market segment, and wishes to supply promotional offers, including discount practices, he shall submit the relevant cost breakdown for the said service and offers for determination by the Authority. (7) Every public operator shall – (a) before entering into a new market or market segment, notify the Authority of its intention to do so; and (b) furnish to the Authority such information relating to its operations as the Authority may require under this section.
