Pollsters have hit back at MPs’ suggestions that they deliberately misled the UK public ahead of the Brexit vote in order to help boost hedge funds’ profits from shorting the pound. In response to a letter from Nicky Morgan MP, as chairman of the Treasury Select Committee, the UK’s most respected pollster, Professor Sir John Curtice, said she had cast doubt on the “professional integrity of the industry”. If private exit polls, which are often commissioned by financial institutions were banned, this would impact not only hedge funds, but also banks, Sir John said.
