Tories warned over 'crossing line' in phone calls to voters

The Conservative Party has been warned over its use of a telephone call centre to contact voters in the run-up to the general election.

The Information Commissioner's Office (ICO) found "two small sections" of the scripts supplied by the party crossed the line from legitimate market research into "unlawful" direct marketing.

The findings follow an undercover investigation by Channel 4 News which claimed workers at Blue Telecoms in Neath, South Wales, may have been carrying out paid canvassing, which is banned under electoral law.

The Conservatives have always denied breaking the law, insisting the scripts it supplied were compliant with data protection and information legislation.
