Special report from Peter Geoghegan, Barcelona
At midnight on Saturday, a huge digital clock on the wall of an apartment block in Plaça Sant Jaume square, in Barcelona, flipped to 00:00:00.
"Fem un pais nou" ("Make a New Country") said a sign next to the timer. Red and yellow Catalan flags were draped across the adjacent balconies. The day of Catalonia's poll on independence had arrived.
