This is a typical Fenland pattern in the late afternoon, aircraft vapour trails, power lines and poles and as always, the poles leaning every which way.
Sometimes we think that the engineers who wire the poles have tightened the wires more than they ought to and this is why the poles lean. More likely it's a combination of high winds and soft ground coupled with the continual cleaning out of the dykes by the drainage board which weakens the resistance of the soil that the poles are in.
Leaning poles are a common sight all over the Fens, so much so that you'd be concerned if you saw a line of them perfectly upright, now that would be very worrying.
If you did see that phenomenon it would probably need an emergency call to get them set at an angle and restore normal service.
