However, Robinson will be released from prison after it was found that his conviction was "flawed".
The cause of the imprisoned founder of the English Defence League has inspired "alt-right" politicians in the USA such as Steve Bannon as well as Geert Wilders, leader of the Dutch populist Party for Freedom.
Robinson has been freed on bail pending a rehearing of the allegation relating to Leeds Crown Court after the finding of contempt was quashed by Court of Appeal judges.
He was previously given a suspended sentence for contempt at Canterbury Crown Court, when a judge told him it was likely he would go to prison if he engaged in similar conduct in future.
United Kingdom judges on Wednesday granted far-right activist Tommy Robinson conditional bail while he appeals a finding of contempt of court for live-streaming outside a criminal trial in violation of reporting restrictions.
Robinson was not present on Wednesday when the Lord Chief Justice Lord Burnett, Mr Justice Turner and Mrs Justice McGowan announced their decision - which was greeted with a round of applause by supporters in the packed courtroom.
The judge determined that Robinson's broadcasting of a video online breached a court order which postponed any reporting of a trial until the conclusion of another, linked, trial.
Robinson is not free forever - a fresh hearing of the case will happen with a different judge.
He was sentenced to 10 months for contempt of court and given a further three months for breaching the terms of a previous suspended sentence.
There are a number of rules governing the reporting of court proceedings and these are aimed at ensuring a fair trial for any accused person.
Mr Dein argued during the recent appeal proceedings that the findings of contempt of court on each occasion should be quashed as a "conglomeration of procedural deficiencies" had given rise to prejudice.
The speed at which proceedings were started also meant Robinson's hastily-found defence lawyer in Leeds had "limited opportunity" to "investigate mitigation" as well as "no opportunity to obtain character references".
They said the judge who jailed him gave "no clarity" about what parts of his Facebook Live video were in contempt of court.
Yesterday supporters outside the Royal Courts of Justice chanted "Tommy's coming home" to the tune of England football anthem Three Lions.
