The NDP is shuffling its upper ranks, bringing in a former political aide to party leader Jagmeet Singh as its new national director.

Melissa Bruno is replacing Robert Fox as the NDP’s national director, according to a statement from the party.

She will become the party’s interim national director starting January 15, and serve in that position until a permanent replacement is chosen after the party’s convention in February 2018.

Bruno was chief of staff to Singh when he was an MPP at Queen’s Park; she also worked on his leadership campaign as an adviser. She headed up Singh’s transition team after he was elected NDP leader this fall.

Fox had been the party’s national director since September 2016, and will stay on with the federal NDP as a special adviser to Singh.
