What is the white thing called and will it just be a simple matter of
removing the toilet and replacing it.

WC pan connector, or commonly known as a Multikwick or Kwickfit IIRC.
Yes, it has a rubber seal around the male end which shoves into the grey
soil pipe, and another one at the female end to accept the ceramic
outlet of the loo.

Available in "straight" or "offset" types (you might be better off with
the latter?):

Especially if you're taking out the toilet anyway to sort this problem,
make sure you put the floor covering underneath it rather than around it
- much better job! NB - this may affect the relative alignment of the
outlet and inlets, depending on the thickness of the floor covering.
