Stephen Yaxley-Lennon (born 27 November 1982), known as Tommy Robinson, is a British far-right and anti-Islam activist.

He has served as a political advisor to the Leader of the UK Independence Party (UKIP), Gerard Batten, since November 2018 and is a co-founder and former leader of the English Defence League.

Robinson has been active in far-right politics for many years.

He was a member of the neo-fascist and white nationalist British National Party (BNP) from 2004 to 2005.

For a short time in 2012, he was joint vice-chairman of the British Freedom Party (BFP).

Robinson led the EDL from 2009 until 8 October 2013.

He continued as an activist, and in 2015 became involved with the development of Pegida UK, a British chapter of the German-based Pegida organisation (Patriotic Europeans Against the Islamisation of the West).

From 2017 to 2018, Robinson wrote for and appeared in online videos for The Rebel Media, a Canadian far-right political website.

Robinson has accumulated several criminal convictions and has served three prison sentences.

His criminal record includes convictions for violence, financial and immigration frauds, drug possession, public order offences, and contempt of court.

He has served at least three separate custodial sentences: in 2005 for assault, in 2012 for using false travel documents to enter the United States, and in 2014 for mortgage fraud.

In May 2018, Robinson was sentenced to 13 months' imprisonment for contempt of court after publishing a Facebook Live video of defendants entering a law court, contravening a court order that disallows reporting on such trials while proceedings are ongoing.

On 1 August 2018, due to procedural errors, he was released on bail pending a new hearing of the case.

On 5 July 2019, Robinson was again found guilty of contempt of court at the retrial and was sentenced at the Old Bailey to nine months in prison on 11 July․ Before his sentencing, Robinson appeared on InfoWars and appealed for political asylum in the United States.
