The BAA needs to be forced to divest both Gatwick and Stansted, as well as either Glasgow or Edinburgh. Only true private competition works in the interests of the customer, and a stitch-up leaving the rest of BAA as a quasi-monopoly by selling Gatwick to MAG is just not acceptable.
MAG is not a private sector company as it is owned by a consortium of councils. As such, it is not fit to purchase other airports outside its area (although it has done so in the case of HUY, EMA and BOH).
The public sector is an inappropriate owner of, well, virtually everything, as it has a tendency verging on certainty to c0ck things up.
Under the leadership of The Blessed Margaret we managed to abolish inefficient public sector entities. Don't lets regress to the chaos of the seventies.
