The Conservative party has denied breaching data protection law during the general election campaign, after Channel 4 claims to have uncovered secret footage of a Welsh call centre hired to directly contact voters in marginal seats.

According to the programme the Conservatives hired Blue Telecoms, a firm in Neath in South Wales to call voters during the campaign.

The Tories said the company was hired to carry out legal market research and direct marketing. But Channel 4 News claimed workers may have been carrying out paid canvassing because they pushed what appeared to be key Tory messages to undecided voters, which is banned under electoral law.

One of the call scripts, seen below, was quoted in the programme.

It was reported in the Daily Mirror in September last year the Jeremy Corbyn is not concerned about the numbers of people coming to live in the UK and it was reported on Sky News this year that Theresa May has restarted her pledge to reduce net migration.

Call Script

Plaid Cymru has called for a police investigation to be carried out into the claims.

These are extremely serious allegations of potentially unlawful activity by the Conservative party. If they are true, then it seems as though the Conservatives may have been trying to manipulate people into voting for them by lying about who they are and why they are contacting them.

The Conservative Party has denied the claims.

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.
