From 10 to 12 September 2011 I visited Barcelona to attend the National Day of Catalonia and give a presentation in the town of Riudecanyes.  The costs of flights to and from Barcelona (£216.54) were met by the Provincial Council of Riudecanyes (the local authority of Riudecanyes of Town Hall Carrer Dimecres, 9 43771, Riudecanyes) and accommodation costs (£200) were met by Esquerra Republicana de Catalunya (a political party in Catalonia and currently the opposition in the Catalonian Parliament of National Office of ERC Calàbria, 166 08015, Barcelona).
