Following the winding up of the Socialist League in 1937 there were attempts by its Trotskyist faction- the group around Reg Groves- to resurrect it as the Socialist Left Federation.
We have issue 1 of The Call- newspaper of the SLF from March 1938 which calls on workers to “Organise the Revolutionary Left in the Labour Party- join the SLF”
(A fragile, large format broadsheet paper we have had to scan each page as two files and then splice them together.)
It is unclear how many issues of The Call were published but by September of 1939 Groves was instrumental in founding a new body- the Socialist Anti-War Front which, a year later in November 1939 was to begin publication of its own newspaper also called The Call.
It is possible that the SLF merged entirely with the SAWF.
We have four issues of “The Call of the SAWF”
By this time, Groves himself had broken with the organised Trotskyist movement but The Call carried articles by a number of those associated with Trotskyism- Harry Wicks, Hugo Dewar, Frank Ridley, Henry Sara…
A letter welcoming the appearance of the appearance of The Call from the Independent Socialist Party (a rightist split from the Independent Labour Party) and pledging adherence to the SAWF shows the intended broad appeal of the SAWF beyond the ranks of Trotskyists.
