At HERA, about 10% of the deep inelastic events present a large rapidity gap in the hadronic final state, attributed to the exchange of a colour singlet system. A pomeron and a secondary reggeon exchange are needed in order to explain the data in terms of Regge phenomenology. A QCD analysis of the extracted structure function for the pomeron exchange indicates parton distributions dominated by a gluon carrying a large fraction of the exchange momentum at low Q{sup 2}. This behaviour is confirmed in measurements of the hadronic final states. The usage of leading proton spectrometers allows the measurement of additional kinematic variables.
