The first convention of a new Yukon political party has been postponed after its founding leader broke his leg while grocery shopping on the weekend.

Willard Phelps, who launched the United Citizens Group as a grassroots alternative to the Yukon's three existing parties, was supposed to preside over the convention in Whitehorse on Saturday.

But Phelps is currently in hospital, recovering from surgery to put a metal pin in his leg.

"I was grocery shopping and I didn't see a place where somebody had spilled Coke or coffee on the floor, and all of a sudden I took a bad fall and broke a leg," Phelps told CBC News on Monday.

"It was actually amazing that it was worse than any fall I've ever had on ice or anything else."

Convention organizers have postponed the convention until more is known about Phelps's medical condition. Phelps said he hopes the delay will be short and the convention can go ahead in a week or two.

Delegates at the convention will elect a leader and executive, as well as formally approved the party's name and constitution, Phelps said.

"We had an excellent meeting up in Dawson and good support up there … we're getting good reception everywhere we go, actually," said Phelps, a former Yukon government leader.

"We really feel that people are starting to understand the need for what we're proposing, which is really a group that really means what it says when it talks about accountability and openness and honesty."
