Yoani Sánchez cannot be in Madrid today after the Cuban authorities she criticises in her prize-winning internet blog, were unable to process her travel visa application in time.
The 33 year old language graduate had planned to fly out to Madrid yesterday to pick up the Ortega y Gasset digital journalism prize, that is awarded annually by El País, but her paperwork was not ready.
Ms Sánchez started her blog - entitled 'Generación Y' - back in 2007.
A prominent Cuban blogger resident in Spain will pick up the prize at today's prize-giving ceremony for which Ms Sánchez has recorded an acceptance speech.
Last week 'Time' magazine included Ms Sánchez in their list of The World's Top 100 Most Influential People list.
