CTV News has learned that Taz Stuart is stepping down as the interim leader of the new anti-tax Manitoba Party, with only a few months before the April 19 provincial election.

The Manitoba Party's platform includes a promise to cut the provincial sales tax to five per cent from eight. The party, which launched last month, also says it would institute a flat income tax of 10 per cent to replace current progressive tax brackets that top out at 17.4 per cent.

The party also says it would scrap the province's business payroll tax, which brings in hundreds of millions of dollars each year.

Earlier this year, Stuart was announced as the interim leader of the new political party. Stuart is a former entomologist for the City of Winnipeg.

More details to come.
