British Columbia's New Democrats have launched a fresh attack on Premier Christy Clark, releasing an ad that casts the new Liberal leader as merely a copy of her predecessor.

The Opposition party has been attempting to ensure the voter anger that forced former premier Gordon Campbell from office doesn't wane just because the Liberal government has a new leader.

In the new ad, a couple sits at the breakfast table eating a fictional cereal called "Christy Crunch," which they agree tastes similar to "Campbell Crunch."

One of the actors complains the new cereal contains "artificial sweetener" before asking: "Can something taste mean?"

The NDP released another attack ad earlier this year during the Liberal leadership campaign, depicting the four front-runners as photocopies of Campbell.

Carole James announced her resignation last December as leader of the provincial NDP. The party will vote on a replacement April 17.
