The watchdog group, Transparency Solomon Islands, says MPs have seriously breached their responsibilities to their constituencies in the way they have distributed flood assistance.
Earlier this month the Solomons' Government gave each MP 40 thousand US dollars which they characterised as their constituency funds, which could be used for disaster relief.
But TSI's Daniel Fenua says the Government used the flooding as an excuse to roll out the controversial constituency money.
"And we think that if that is what they intend to do, like with the 300 thousand, is to help the flood victims, then they are supposed to channel it through an appropriate authority rather than giving it to all MPs, where you can clearly see, only a number of MPs in their constituencies have been affected."
