Why is the PAP MP Focused on Heritage?

A few days ago, PAP MP NairaZohrabyan in an interview with Lurer.com expressed the opinion that Heritage is not an independent political force; it is a controlled political force.
Today Heritage party speaker Hovsep Khurshudyan in the interview with Lurer.com-commented on Zohrabyan’s this view, saying: "Look, the force that declared itself as an alternative to the authorities, voted for Hovik Abrahamyan, for the latter to become NA chairman, makes a number of votes consistent to the RPA position, including the release of additional tens of millions of cubic meters of water from Sevan, with its absolute majority avoided joining the deputy signature gathering concerning Harsnaqar, finally, indirectly took ministerial portfolio, and still retains the positions of deputy ministers and governors. And it is very comprehensive why instead of criticizing RPA she focused on Heritage. Prbably Naira Zohrabyan considers serious especially this behavior. The ironic part is that the representative of a party which demonstrates similar behavior accuses Heritage in being “controlled”,” Khurshudyan stated.
Today in the interview with us Naira Zohrabyan advised Hmayak Hovhannisyan- the chairman of Political Union, not to regard Heritage seriously. To Zohrabyan’s such observation Khurshudyan answered: “Probably the PAP MP considers serious the absence of the whole group from country, when NA session is not over yet. And probably it’s more serious to her, that the PAP, being a part of the governing coalition during the last 5 years, by holding hands with RPA and making even worse the RA citizens’ already inconsolable social conditions, using the created situations, on the election day, with the same RPA, using the fact of thousands of people’s bad conditions, received votes with election bribes and false illegal charities
If the PAP MP considers this to be “serious”, then it’s understandable why has she focused on “Heritage” and why she doesn’t regard seriously to the fact that we can be happy for her.
