Jayda Fransen,  the Britain First leader whose videos about Muslim atrocities were retweet by President Trump in November of last year, is in jail in the UK for "religiously aggravated harassment", i. e. free speech, and protesting Muslim rapists.

I learned that she can receive mail and letters in prison.

Her address in prison is as follows:

PRISON NO: A7921EDFRANSEN

ADDRESS: HMP Bronzefield, Woodthorpe Road, Ashford, Middlesex, TW15 3JZ

United Kingdom

Send her an actual letter of support via old-fashioned postal mail.
