After months of speculation, Gabriel Nadeau-Dubois confirmed Thursday he wants to take a leadership role with the small, left-wing party Québec Solidaire.
The 26 year old said he will seek the party nomination in Gouin, the former riding of Françoise David, as well as the role of party spokesperson.
"It's the only party where I feel at home," he said at a news conference.
The party has made no secret of trying to recruit the charismatic figure.
David, one of the party's founders, suggested he would be a good fit for the party when she quit politics in January for health reasons.
Nadeau-Dubois said he wants to make the party younger, more diverse and expand beyond its base in the Montreal area.
"We have to do it together. Come work with us to change Quebec," he said.
Manon Massé, the MNA for Sainte-Marie–Saint-Jacques, is also seeking a position as party co-spokesperson.
Since leaving student politics, Nadeau-Dubois has published a book, Tenir tête, which won the 2014 Governor General's Literary Award for non-fiction.
Last fall, Nadeau-Dubois was among several other prominent progressives who held discussion forums across the province about changes they wanted to see in Quebec society.
Nadeau-Dubois has plenty of work ahead with Québec Solidaire.
The party holds only two seats at the National Assembly and finished fourth in the 2014 provincial election, with only eight per cent of the popular vote. No date has yet been set for the byelection in Gouin.
