(1)For the purposes of this Chapter a person shall be taken to have significant market power in relation to a market if he enjoys a position which amounts to or is equivalent to dominance of the market.
[F297 (2)References in this section to dominance of a market are to be construed, so far as it is appropriate to do so for the purposes of this Chapter, in the same way as the reference in section 18(1) of the Competition Act 1998 to a dominant position in a market.F297]
(3)A person is to be taken to enjoy a position of dominance of a market if he is one of a number of persons who enjoy such a position in combination with each other.
(4)A person or combination of persons may also be taken to enjoy a position of dominance of a market by reason wholly or partly of his or their position in a closely related market if the links between the two markets allow the market power held in the closely related market to be used in a way that influences the other market so as to strengthen the position in the other market of that person or combination of persons.

199.Sections 78 to 93 concern OFCOM’s powers and duties to identify markets, determine whether persons have significant market power (SMP) on those markets, and to impose SMP conditions on persons whom they have determined as having SMP.
200.Section 78 sets out when a person shall be taken to have SMP in relation to a particular market. A person will only be taken to have significant market power where he is, alone or with others, in a position of dominance in a market. A position of dominance must be construed in accordance with any applicable provisions of Article 14 of the Framework Directive, which (at its paragraph 2) defines dominance as ‘a position of economic strength affording the person the power to behave to an appreciable extent independently of competitors, customers and ultimately consumers’. A determination of joint dominance must take into account, in particular, the criteria for joint dominance set out in Annex II to the Framework Directive. This implements Article 14 of and Annex II to the Framework Directive.
