Internet trolls will face up to two years in jail under tough new laws proposed by Justice Secretary Chris Grayling.
The previous maximum term of six months will be quadrupled under the plan to tackle the "cowards" who post abusive comments online.
Mr Grayling said the plan was a signal of his determination to "take a stand against a baying cyber-mob".
The move comes just days after the threats directed at Chloe Madeley after she stepped in to defend her mother Judy Finnigan's controversial comments about footballer and convicted rapist Ched Evans.
The Justice Secretary told the Mail on Sunday: "These internet trolls are cowards who are poisoning our national life."
