Although a little hard to read, the reg is
F-BXCP which you can find with a search
The aircraft is a Max Holste MH.1521 Broussard which is a 1950's era aircraft originally built for the French airforce.
Somewhat interestingly that aircraft is now registered
G-HOUR and is owned by the luxury watchmaker "Bremont" (hence the reg). It seems to have first got a reg-change with the same paint scheme and then latterly been repainted.
