I have been lifting up concrete that was in my back garden, and the
soil/clay under it is blue, sticky and doesn't allow the rainfall to
drain. Is there anything i can do to improve the drainage?




IMO, short of getting a JCB in to remove it and replace it with topsoil, no.
That's assuming you want to cultivate it. You can try land drains, and
digging in lots of good compost, leaf mould, etc. But they will all
disappear over time to be swallowed by the clay.

If you just want to get the rain to drain away without cultivating the land,
just dig out the top few cm and put down gravel or stone chippings to the
same depth. These will also get swallowed over time, but will last many
years.
