Victoria Thomas Bowen, from Clacton-on-Sea, Essex, is set to appear at Westminster Magistrates’ Court in London this morning. She is also accused of criminal damage as well as the assault charge.
Mr Farage, 60, was covered with a drink as he left a Wetherspoons pub in Clacton-on-Sea on 4 June.
Prosecutors allege that £30 worth of criminal damage was caused to a jacket belonging to a member of Mr Farage’s team.
Caroline Liggins, representing Ms Bowen, said: “My client strongly protests her innocence and looks forward to fighting these unjust charges in court.”
Nigel Farage is now the MP for Clacton after winning the seat in the 4 July election with a majority of 8,405.
