"This price [rise] does not reflect the real cost as it does not take into account increases in the price of NGV," she said.
Meanwhile, the network of taxi cooperatives in Bangkok yesterday demanded a 13% second-phase fare hike and a freeze on NGV prices.
"If the government fails to approve a 13% second-phase rise or if no other subsidy measures are rolled out, the same problems of us rejecting customers will occur," network chairman Witoon Naewpanich said.
The Transport Ministry has approved a 5% second-phase taxi fare rise, which will take effect in April.
An 8% first-phase rise took effect in December.
