Spratt, who joined MHP from Cohn & Wolfe this time last year, has been made a partner at the agency and reunited with his former colleague and existing Pagefield partner Kate Levine in the PR team.
His appointment coincides with the recruitment of three new consultants: Geoff Duggan from Porter Novelli; Samantha Vogts from Baldwin Boyle Group and Benjamin Thiele-Long, a former criminal barrister. Rory Cronin, meanwhile, has been promoted from executive to consultant.
Pagefield founder and senior partner Mark Gallagher said: "The first quarter of 2014 has seen rapid growth for Pagefield. I am delighted we’re able to attract really high-calibre people to strengthen the backbone of a great agency."
The agency has also announced a new service, Pagefield Advisory, which offers discreet counsel, training and support in the political and media arenas.
Pagefield chairman Sir Christopher Meyer said: "Pagefield Advisory is an offer we have been developing for some time and I’m delighted that we have an extraordinarily strong team of senior advisers with outstanding contacts and experience. I really don’t think you’ll find senior counsel of this stature elsewhere."
Other people moves include the promotion of Tom Bage, who joined the agency as a consultant in 2012, to associate partner, and graduate interns Sam Oakley, Fred Azis-Laranjo and Nathan Jones to executive level.
The agency now has more than 30 full-time staff, supported by 20 specialist partners and senior advisory board directors.
