One of the radical book trade successes of last year was the first London Radical Book Fair, which attracted 50 publishers and booksellers to London's Conway Hall in May.

To everyone's surprise - and pleasure - the venue proved to be too small for the crowds and this year the fair moves to the Bishopsgate Institute in the capital on May 10.

There is already a long-standing radical book fair in Edinburgh run by Wordpower Books. In Nottingham, Five Leaves Publications will be organising a one-day event in the autumn in conjunction with the local People's Assembly but at the Bishopsgate fair you'll find more radical publishers and booksellers in one space than anywhere else over the year.
