Sorry, but no, Mary. This happens to many poorly grafted trees and they don't grow well anyway.

Have you had it long Mary, some suppliers guarantee their stock, may be worth you asking them?

thanx to you all. i have now thrown it in the green recycling bin. i think it was beyond saving. we hadnt staked it and the winds over the last few week when i was on holiday proved too much. never mind, being a gardener i am ever optomistic so i will try another!
