Every topological group G has, up to isomorphism, a unique minimal G-flow that maps onto every minimal G-flow, the universal minimal flow We show that if G has a compact normal subgroup K that acts freely on and there exists a uniformly continuous cross-section from to then the phase space of is homeomorphic to the product of the phase space of with K. Moreover, if either the left and right uniformities on G coincide or G is isomorphic to a semidirect product , we also recover the action, in the latter case extending a result of Kechris and Sokić. As an application, we show that the phase space of for any totally disconnected locally compact Polish group G with a normal open compact subgroup is homeomorphic to a finite set, the Cantor set , , or
