It seems that the systemic establishment recruits independent MPs who suddenly join the government when things become risky for its dominance
by system failure
Disorientation operations continued by the government through the "fresh milk" case and the supposed "rebel" MPs declaring that they will not retreat (http://www.keeptalkinggreece.com/2014/03/21/greeces-coalition-government-at-risk-to-drown-in-fresh-milk/), but it is almost certain that they have already agreed to follow Troika's orders, adopting new IMF-type measures of destruction.
These operations, however, are risky because one or two MPs who really want to abandon government in order to be rescued against a political death, may follow the supposed "rebels". Therefore, as the government has a tenuous majority, there is a danger that the new bill will not pass from the parliament in the next few days.
Thus yesterday, "accidentally", two MPs of the Right moderate nationalist party "Anexartitoi Ellines" - who is against Troika's policies - announced that they are leaving the party (http://www.tovima.gr/en/article/?aid=580401). The decision came a few days before the new bill through which the interests of multinational cartels will be further promoted in various sectors.
The - now independent - MPs will be probably recruited to vote for the bill in case that one or two government MPs refuse to vote it, and it's quite possible to join the leading government coalition party, "Nea Dimokratia", after the bill.
Besides, It will not be the first time that something similar happens. The Markopoulos-Soldatos case is characteristic, since after leaving Nea Dimokratia, they re-elected with “Anexartiti Ellines” political party, in order to validate their stance against catastrophic policies imposed by the Troika lenders, but in the first chance, left from party and stayed in ice as independent MPs, in order to be ready for their come back to “Nea Dimokratia”:
A possible scenario? We will probably find out in a few days.
