The pork pies were handed to journalists in the press room by 'butchers' wearing Brown face masks, shortly before David Cameron's unscheduled speech to the party faithful.
The locally made pies were also available from a stand in the conference centre and were so popular that they ran out shortly after midday of the first day of the conference.
A leaflet accompanying the free pies stated: ‘Gordon Brown has been feeding Britain porky pies for over a decade - and he never tires of coming up with new porky pies to stuff down the nation's throats.'
A Labour Party source dismissed the excercise as a 'juvenile stunt'. The source added: 'If the Tories really think journalists will swallow this kind of spin they are not living in the real world.'
