The election of hardline federalist Pierre Elliott Trudeau as Prime Minister, and the politically damaging riot instigated by the RIN when he appeared at the St. Jean Baptiste Day parade of 1968, led to the sovereignty movement coming together. The MSA would merge with another party in the Quebec sovereignty movement, the Ralliement National of Gilles Grégoire, to create the Parti Québécois (PQ) in 1968. At Lévesque's insistence, RIN members would be permitted to join but not be accepted as a group.
