In this scenario the intergalactic magnetic field has a strong (m Gauss) regular component spanning tens of Mpc. This could have severe consequences on the propagation of ultra-high energy cosmic rays, and the observed spectra, isotropy and composition. A quantitative discussion of these effects is given in the present work.4 pages, talk at 16th ECRS, University of Alcala, in pressAstrophysicstext
