Now it's important not to jump to conclusions, but it does rather look like the Met are carrying out preliminary survey work in preparation for submitting its planning proposals - before their 'consultation' is even close to finishing on 25 September.
If there is a more innocent explanation, perhaps someone could enlighten me. But if the police really are rushing ahead, why go through the pretence that local people's opinion actually matters?
Thanks to Dave of the East End Howler for the photos
There IS an entirely innocent explanation - the Showmen's Guild is marking out the pitches for the forthcoming Wanstead Flats Fair. I've never seen this before, so thanks to Paul Thomson (the Superintendent of Epping Forest, no less) for e-mailing to provide some reassurance.
