It's only been three months since the consumption tax was hiked to 8 percent, but the ruling coalition is already expediting talks on another increase scheduled to come into effect in October next year.

Concerned that the tax hikes could harm consumer confidence, the ruling camp is mulling ways to alleviate the impact on low-income households, possibly by reducing the tax rate on daily necessities.

European countries have implemented such a system, but it has not been credited as an effective way to reduce the burden on the poor.
