      abstract     = {Highly polarised, high current electron bunches from
                      compact laser-plasma accelerators are sought after for
                      numerous application. However, current proposals to produce
                      these beams suffer from intrinsic limitations to the
                      reproducibility, charge, beam shape and final polarisation
                      degree. We propose colliding pulse injection as a technique
                      for the generation of highly polarised electron bunches from
                      pre-polarised plasma targets. Using particle-in-cell
                      simulations, we show that colliding pulse injection enables
                      accurate control of the spin-polarisation during the
                      trapping of electrons, enabling high-current electron
                      bunches with high degrees of polarisation to be generated.
                      Bayesian optimisation is employed to optimise the
                      multi-dimensional parameter space of colliding pulse
                      injection, demonstrating the generation of highly polarised,
                      high-quality electron bunches employing 100-TW class laser
