The Conservative Party has denied claims that it used a Neath call centre to canvass voters during the general election.

 A Channel 4 investigation claimed that Blue Telecoms conducted marketing campaigns ahead of the general election, under contract of the Conservative Party. Paid canvassing is banned under electoral law.

The investigation claims that workers promoted Conservative messages to undecided voters in key marginal seats, including Clwyd South Wrexham, Gower and Bridgend.

 The Information Commissioners Officer confirmed it would be asking the Tories about the calls.

 A Conservative Party spokesperson said all calls were compliant with the law, and that “Political parties of all colours pay for market research and direct marketing calls.

 “All the scripts supplied by the party for these calls are compliant with data protection and information law.”

 “We will be asking the Conservative Party about the marketing campaigns conducted from this call centre,” a spokesperson for the Information Commissioner’s Office said.
