MADRID, July 29 (Reuters) - Spain's antitrust regulator

said on Tuesday it was expanding its investigation into possible

anti-competitive behaviour by Apple ( AAPL ) for allegedly

imposing unequal commercial conditions on developers of mobile

applications sold at its app marketplace.

The wider probe will examine whether the tech giant set

pricing schedules at its App Store, abusing its dominant

position, the CNMC said in a statement.

Apple ( AAPL ) has denied the allegations since the CNMC launched its

investigation a year ago.
