The upper limit of 20% above which government approval was needed for the acquisition of shares of firms under government control was repealed in 2012. There is no public owned company in the sector. Moreover, it has to be taken into consideration that even if there was a public owned company, since there is a 49% foreign ownership limitation, this will also affect the ability of foreigners to own share in publicly-controlled firms. Note however that Ministerial Decision on air transport companies ΥΑ Δ1/Δ/30817/2180 stipulates that the latter requirement of minimum 51% national ownership may not be satisfied if this is imposed by a general governmental policy.
