Esper Liberation Front, from the Deathstalker novels by Simon R. Green.
When it was discovered that Espers existed (esecially telepaths, but also including telekenetics and the like) they were enslaved by The Empire. E.L.F. struggles to free them, in an often spectacular but mostly useless manner.
The most deadly strike by the Empire against the E.L.F. was, of course, Typhoid Mary.
