The brief involves consulting with MPs in Westminster and the regional assemblies over the commission’s strategy to convince the electorate about the need to vote.
In addition, it will promote its policies to modernise electoral law, which include the introduction of a UK-wide electronic register and standardisation of polling hours for all elections.
The brief also includes highlighting the commission’s regulation of political parties’ expenditure.
Westminster Strategy won the business after a pitch against LLM Communications and Lexington Communications.
The hire was made by Electoral Commission director of comms Angela Salt, who joined three months ago from Grayling, of which Westminster Strategy is a part. Salt was not personally involved in the final decision.
Salt said the body would use the agency until the end of March, by when she plans to have appointed a PA manager responsible for ‘stakeholder engagement’.
