Two suspects have pleaded guilty to sending threatening tweets to British journalist and feminist campaigner Caroline Criado-Perez.

Isabella Sorley, 23, of Newcastle, and John Nimmo, 25, of South Shields, admitted at Westminster Magistrates' Court to sending the messages over the social media site.

They were arrested under the Communications Act 2003 for sending abusive tweets to s Criado-Perez, 29, after she successfully campaigned for author Jane Austen to feature on the new £10 note.

She instigated her campaign to keep a woman on bank notes after the Bank of England revealed that social reformer and philathropist Elizabeth Fry would no longer appear on the new £5 note in favour of Winston Churchhill instead.

Sorley and Nimmo sent the tweets - which included threats of rape - in July after the bank's governor, Mark Carney, confirmed that Austen would replace Charles Darwin on the £10 note.

Criado-Perez called her victory a "brilliant day for women".

The Walthamstow MP Stella Creasy and historian Prof Mary Beard were also targeted after they supported Criado-Perez.

Sorley and Nimmo face sentencing on January 24.
