Premier Christy Clark says she agrees with voters who say the question on the HST referendum is confusing.

People who want to dump the HST will vote "yes," while those who support the tax will vote "no."

Clark says the question that Elections BC approved was set by former premier Bill Vander Zalm and one-time NDP strategist Bill Tieleman, who launched an anti-HST campaign and forced the referendum.

Clark says she won't be pitching a big sales campaign for the HST, which the Liberals pledge to reduce from 12 per cent to 10 per cent by July 2014.

She says it's up to British Columbians to make their own choice on whether to keep the tax but going back to the PST and GST would leave a $3-billion hole in the provincial budget.

Referendum ballots will be arriving in mailboxes over the next two weeks and must be returned to Elections BC by July 22.
