Philip Cowley, Professor of Politics at Queen Mary has written an opinion piece for the Times' Red Box on the upcoming London mayoral elections and the online poll by the Mile End Institute. He writes: "That’s the main finding from an online poll by the Mile End Institute and YouGov between March 29 and April 1. Our total sample size was 1,192 adults. The figures have been weighted and are representative of all London adults aged 18 and above."
