Interest in next Sunday's general election has grown over the past week, but 44 percent of voters are still not sure which party to vote for, a Kyodo News poll showed Sunday.

Of the 2,000 respondents to Kyodo's second pre-election telephone poll conducted Friday and Saturday, 67 percent said they are interested in the House of Representatives election, up 7 percent from the previous poll June 9 and 10.

In the proportional representation section where voters must choose a party rather than a specific candidate, 17 percent said they will vote for the ruling Liberal Democratic Party, which occupied 271 of the chamber's 500 seats before its dissolution on June 2.
