The sovereigntist party has announced its star recruit Daniel Paillé at a news conference.

Bloc Leader Gilles Duceppe said Paillé will become an economic advisor in his office while also seeking a nomination to run for the party in the next election.

Paillé hopes to land the Bloc nomination in Montreal's Hochelaga riding.

When he was appointed in 2007 and given a $1-million budget to examine the polling practices of the former Liberal government, Harper's opponents screamed conflict of interest.

They complained that Paillé — a former Parti Québécois provincial minister who worked on the Yes side in the 1995 Quebec referendum — had been granted unfettered access to the books of his federal opponents.

In the end, though, Paillé's report was mild on the ex-Liberal government and actually slammed the Conservatives for getting carried away with public-opinion polling.

Duceppe and Paillé both say his previous work as a federal investigator posed no conflict of interest.
