Clark made her intentions known in a brief statement on Friday, and will also be giving up her seat in Kelowna.
"Although we respect her decision, we are deeply disappointed".
"Rich and the B.C. Liberal caucus will get to work preparing for the recall of the legislature and will shortly provide details of critic appointments", the statement said. A last minute shift in policy to include key points laid out in election platforms of both the BC NDP and BC Greens did nothing to alter public perception following the throne speech, which paved the road for a non-confidence vote.More news: Northwestern Professor, Oxford Clerk Arrested In Stabbing Murder
Letnick acknowledged Clark had her detractors as is normal within a partisan political system, but hoped those of all political stripes would be able to say thank you to someone who devoted "a good part of her life and time away from her son", to improve the lives of British Columbians. "We're going to focus on what's important for B.C. - jobs, the economy, sending the right message internationally, tracking investment for the people of British Columbia, the people we care about, that's our children, grandchildren, families and communities".
"As I have seen firsthand over the years, she has been fierce, tireless, and immensely generous in building one of the strongest provincial political parties in the country - and deserves our lasting appreciation and gratitude". "I am so proud of everything our B.C. Liberal team has accomplished".
The liberals have to set a date for a leadership vote within the next month.
Clark had said she was ready to serve as the leader of the opposition, after the NDP and Green Party announced their plans to topple her government. That prompted a long legal battle that ended when the Supreme Court of Canada ruled in favor of teachers, which prompted a huge make-up effort to hire more staff and restore previous working conditions that is still underway.More news: Rohani Sworn In For Second Term
She mounted a failed effort for the Vancouver mayoralty, then became a radio talk-show host until 2010. She later won a byelection in Kelowna-Westside, now Kelowna West.
Clark's Liberals governed British Columbia for a total of 5,869 days or 16 years.
She gained prominence in Gordon Campbell's Liberal Party where she was promoted to deputy premier and education minister.
But she couldn't pull off a majority government in the election this May, winning just 43 of the 87 seats in the legislature for a minority government.More news: Euro jumps to January 2015 highs on European Central Bank speculation
The truest signs of leadership, whether it's politics, business or sports, is putting others first, by crediting everyone else for the wins and taking sole responsibility for the loses.
