Hedlund resigns Senate seat ahead of Weymouth mayoral inauguration

BOSTON — Set to become the next mayor of Weymouth in a little more than a week, state Sen. Robert Hedlund on Thursday formally filed his intent to resign his seat on Jan. 4, a step required before the Senate could consider scheduling special election next year.
Hedlund, a Republican who was elected mayor of the South Shore town back in November and is due to take the oath of office a week from Monday, opted against filing the irrevocable letter sooner, which could have allowed the Senate to set a special election to coincide with the state's March 1 presidential primary as the House did to fill Fitchburg Mayor-elect Stephen DiNatale's seat.
