Danny Williams going to U.S. for heart surgery

Newfoundland and Labrador Premier Danny Williams is set to undergo heart surgery this week in the United States.

CBC News confirmed Monday that Williams, 60, left the province earlier in the day and will have surgery later in the week.

The premier's office provided few details, beyond confirming that he would have heart surgery and saying that it was not necessarily a routine procedure.

Deputy Premier Kathy Dunderdale is scheduled to hold a news conference Tuesday morning.

She's expected to provide more details about Williams's condition, as well as how the provincial government will function during his absence.

CBC reporter David Cochrane said Williams appeared to be in good health recently. He described the premier as "fairly active," playing pick-up hockey at least once a week when work permits.
