Last year I cleared a bed of everything, including grape hyacinth bulbs, and added new soil and re-planted it with pink flowers/plants. This year the grape hyacinths are back in profusion more than ever and the pink plants are being smothered. Please can you help?

It is very hard to get rid of grape hyacinth. Likely, last year, they spread seeds and very small bulblets which you would not have been able to see. They need to be handpulled to be removed. You will likely also need to do this next year as well. Make sure that they and any other grape hyacinth nearby do not go to seed. Remove the spent blossoms before they produce seed pods and this will help keep the spread of them down.
