Sir Robin Bogg is one of the most talked-about figures in the voluntary sector. As chief executive of the British Umbrella Backing Body (BUBB), he blogs regularly, detailing his struggles with other senior figures such as his nemesis Sir Hubert Carrington of the National Canopy and Visor Organisation (NCVO) and Social Enterprise London's Hillda Ogden-Newton&Ridley.
On Friday 1 April, Sir Robin will be here to take your question on the umbrella sector – and who knows, maybe a question or two on the voluntary sector too.
Post your questions below, and don't forget to come back on Friday 1 April from 1100 - 1200 to join in what promises to be a unique - and possibly unrepeatable event
