Rahul's brain hasn't matured with age: Modi

New Delhi, April 14 (IANS) Attacking Rahul Gandhi for terming the Gujarat model of development a "toffee model", BJP prime ministerial candidates Narendra Modi Monday said the Congress vice president lacks a mature brain and thinks like a child.

"Don't go by his (Gandhi) age, he hasn't matured mentally and that's why kept talking about toffees," Modi said while addressing the second round of 3D rallies to around 100 locations in 15 states.

"He is a child at heart because if he was mature he would have known that over 300 models of the Gujarat government has won toffees (trophies) from the United Nations and the Indian government," he added.

Gandhi Monday termed the Gujarat model of development as a "toffee model" as land of poor farmers was being sold to industrialists at throwaway rates - the same as a toffee costs.

Addressing a massive election rally in Maharashtra's Latur town, he alleged that in Gujarat only one industrialist was benefitting at the cost of the poor farmers and labourers who are dying of hunger.

Using 3D holographic projection technology, the rallies are an attempt by Modi to reach out to as many people as possible by using specialized camera techniques which offer a live-viewing experience without use of 3D glasses. The first round of rallies took place April 11 in over 20 states.
