COLNE Valley MP Kali Mountford delivered postcards calling for fair trade to Valerie Amos, International Development Secretary.
Hundreds of postcards from all over the Colne Valley were posted to Ms Mountford from church members and individuals.
She said: "More than 20 people came to see me in Slaithwaite Civic Hall, to discuss their concerns about people living in poor countries around the world."
Baroness Amos said:
"The trade justice movement brings thousands of people together to express their concern about fair trade to help people worse off than ourselves.
"This gives us more power to negotiate better deals for developing countries."
