You may reverse around the corner here (2 photos below). This corner is much less than a right-angle, so it is very easy to get caught against the kerb. As always it is best to focus down the road behind you.
This is another corner you may reverse around. This is on the airfield side of the town, and as can be seen from the photo below, the corner is very wide. As usual for this type of corner it is best to confirm your position by using the left door mirror, as you follow the kerb around. The road you are reversing from is quite narrow so be extra careful to look out for approaching traffic.
