The federal government has appointed the parliamentary librarian as the interim parliamentary budget officer, until a replacement for Kevin Page can be found.

Page’s term ends this month. He has found himself frequently at odds with the government, criticizing the cost of the Afghanistan mission, the F-35 fighter jet purchase plans and other major projects.

Late last year, Page took the government to court, saying the Conservatives repeatedly refused his requests for information about austerity measures.

Members of Prime Minister Stephen Harper’s cabinet were often publicly critical of Page.

Foreign Affairs Minister John Baird said the budget officer “has overstepped his mandate” and Finance Minister Jim Flaherty once called Page “unbelievable, unreliable and incredible.”

The job posting for Page’s replacement says the government is looking for a “tactful and discreet” parliamentary budget officer who is good at “achieving consensus.”

In the meantime, current parliamentary librarian Sonia L’Heureux will serve as the interim budget officer.
