The fight for Chingford: Is Labour on track to unseat IDS?
During his time running mayoral campaigns for Boris Johnson, Lynton Crosby famously created the "doughnut" strategy. This focused campaigning efforts on the outer boroughs of London where the Tory vote was then strongest. On the face of it, this remains the case. Of the 23 London constituencies that share a border, Labour hold just seven compared to the Tories' 13. But this is up two for Labour from 2015. There are four seats in north and east London where the Tory majority is under 5,000 (five if you include Johnson's majority of 5,034 in Uxbridge). In these, the swings at the 2017 general election range from 2.7% in Hendon and seven percent in Chingford and Woodford Green.
