  An exact solution of Einstein's equations which represents a pair of
accelerating and rotating black holes (a generalised form of the spinning
C-metric) is presented. The starting point is a form of the Plebanski-Demianski
metric which, in addition to the usual parameters, explicitly includes
parameters which describe the acceleration and angular velocity of the sources.
This is transformed to a form which explicitly contains the known special cases
for either rotating or accelerating black holes. Electromagnetic charges and a
NUT parameter are included, the relation between the NUT parameter $l$ and the
Plebanski-Demianski parameter $n$ is given, and the physical meaning of all
parameters is clarified. The possibility of finding an accelerating NUT
solution is also discussed.
