Two individuals have been charged in relation to offensive tweets allegedly sent to feminist campaigner Caroline Criado-Perez.
They will have to travel down from their homes in the north east to appear at Westminster Magistrates’ Court on 7 January 2014.
Labour MP Stella Creasy, who helped with the campaign, also received offensive tweets.
Two other individuals were arrested as part of the same inquiry.
The CPS concluded that it was not in the public interest to prosecute the fourth suspect, who allegedly sent offensive messages to Criado-Perez.
Police are continuing to investigate a fifth suspect before deciding whether to charge them.
