I have just received a press release from the Electoral Commission regarding the count at Tower Hamlets. Buried at the bottom under "notes to editors" is the following point (my emphasis)
Prior to the elections, the Returning Officer for Tower Hamlet put in place a local protocol which represented a commitment by all parties, individuals and organisations involved in the May 2014 elections in Tower Hamlets to work towards free and fair elections. The Electoral Commission and the Metropolitan Police supported this protocol. As part of this protocol, a dedicated email address was set up to allow campaigners and parties to report any incidences of electoral irregularities. The full protocol is available here.
It's a sad state of affairs, when in a London borough in 2014 we are "working towards free and fair elections..."
What a disgrace.
