YouGov sat on 2017 poll as it was too positive on Labour, claims ex-employee

Polling firm denies allegation it drew back from publishing some data showing Corbyn's Labour doing well

YouGov suppressed polling in last few weeks of the 2017 election campaign because it was too positive about Labour, a senior former employee has said.

Chris Curtis, a former political research manager, said everybody panicked at the backlash" to a YouGov poll suggesting there could be a hung parliament, and the firm subsequently drew back from publishing some data that showed Jeremy Corbyn's Labour doing well. YouGov denies the allegation.
