Helen Lawrence, Twitter’s head of creative agency development EMEA, has been promoted to the platform’s global head of social media.

Lawrence, who has held the EMEA agency role for the past year, will relocate to San Francisco for the position. She will be tasked with leading Twitter's multi-channel social media campaigns and editorial globally when she officially begins on 26 February.

Twitter is yet to confirm her replacement in EMEA.

Joining the social network in 2014, Lawrence previously headed up its work with creative agencies in the UK in her first three years at the company.

She initially came on board from BBH, where she was social strategy lead, and has also directed social and mobile departments at Asos and Dare.
