Former Gopeng Umno Wanita chief Hamidah Osman has warned Prime Minister Najib Abdul Razak not to "burn the country" after she was sacked from the party.

"Don't burn the country; if we get burned, he (Najib) will also burn with us," Hamidah told a press conference in Ipoh today.

Hamidah said she had conveyed the message by text message directly to Najib but received no reply.
