In a special edition of You and Yours, we're examining the widespread impact of the volcanic debris which has shut down UK airports. Julian Worricker talks to our panel of experts to examine * how long the shutdown might last * what your rights are regarding compensation * the impact on global commerce. We hear how the head of IATA, the International Air Transport Association, has called the flight ban "a European embarrassment". We'll bring you the latest from Cobra - the Government's civil contingencies committee who are meeting this morning to discuss mobilising the Royal Navy to rescue stranded passengers. We speak to British people around the world who are still stranded and we find out how others are turning to ferries, trains - and bicycles - to get home. Let us know how the flight shut-down has affected you.
