Spain has suspended visa-free travel and reinstituted border checks ahead of a meeting of the European Central Bank.<br /><br />It is an unprecedented move that over-rides the Schengen Protocol that was first instituted in 1985.<br /><br />The agreement means there are no internal border controls for 26 European countries and a population of more than 400-million people.<br /><br />Spain says it needs to regulate its borders to prevent foreign protesters disrupting the ECB meeting in Barcelona next week.<br /><br />It is not the first time Schengen has been called into question - Germany and France also want new rules to make it easier to suspend passport-free travel.<br /><br />Sonia Gallego reports from Madrid.
