BRUSSELS (Reuters) - German builder Hochtief (>> Hochtief) secured unconditional EU antitrust approval on Tuesday for its bid to buy Spanish airports and motorway operator Abertis (>> Abertis Infraestructuras).

The European Commission said the takeover bid raised no competition concerns, confirming a Reuters report on Feb. 1.

Hochtief, majority-owned by Spanish builder ACS (>> ACS Actividades de Construccion y Servicios), is battling Italian airports and motorway operator Atlantia for Abertis. The EU antitrust enforcer approved Atlantia's offer last year without asking for concessions.
