Elain Tappin has given evidence to the Home Affairs Select Committee about her husband Christopher Tappin's extradition to the US.
Mrs Tappin described the "utter disbelief" and "desolation " the family felt when the UK did not stop his extradition.
There was a temporary pause in the reading of her statement as she broke down in tears.
Mrs Tappin also said it should be right as a UK citizen to put your side of case before being picked up out of your life and flown to foreign country.
