Tim Murphy, Newfoundland and Labrador's deputy chief of staff to the premier, has resigned.

Dwight Ball appointed Tim Murphy to the post of deputy chief of staff following the provincial election in November 2015.

Murphy had worked with Chevron Canada for the preceding decade, and had been a high-ranking civil servant with the Newfoundland and Labrador government for nearly 20 years before working in the oil industry.

A spokesperson for the premier's office said Murphy found the political role "wasn't for him" and "not the sort of challenge he was looking for right now."
