The mayor of London in January 2016 re-zoned Stratford and neighboring East London tube stations into zone 2/3 from previously charged zone 3.  Why is it that Seven sisters which is slightly less distance from central London (Charing Cross) still relegated to zone 3 status and residents of Tottenham have to pay more?  The argument by the mayor is regeneration and London is 'moving east'. A huge amount of regeneration is taking place in Tottenham as well so if you find this unacceptable please sign my petition and help make Seven Sisters at least a 2/3 station like the ones in East London.
