An engineering company that wants to build a 40 billion pound airport on sandbanks off Deal on the Kent coast has outlined its scheme - to a French audience. Beckett Rankine were invited to explain the proposal to business leaders in Calais.

Derek Johnson speaks to French business representatives Vincent Didry and Thaddee Segard, Hilary Newport from Protect Kent and Tim Beckett from marine consulting engineers Beckett Rankine.
