Killa's work on the account is led by founder Richard Lamballe, while BPPR chief executive Shimon Cohen oversees his agency's efforts. Both report to Rupert Daniel, FIFA Marketing sales and marketing manager.
The increase in campaigning comes as the Football Fans Union warned that it will attempt to sabotage advertising during ITV's coverage of the tournament as it steps up its PR campaign against ITV networks Carlton and Granada.
The FFU, which officially launches this summer, commenced its 'Can the Commercials' PR drive last week in protest at Carlton and Granada-owned ITV Digital's decision to renege on its broadcast deal with the Football League.
Now the FFU is to extend the protest to cover the final week of the Premiership season, coverage of the First Division play-offs on ITV1, and the World Cup.
The body encourages fans to turn off the TV during ad breaks in ITV's football coverage, in an effort to deter advertisers and affect Carlton and Granada financially.
The FFU is working with consumer-oriented agency Idea Generation to increase awareness of the campaign, which is backed by the League and the Professional Footballers' Association.
