It is understood that Simon Davies, the group marketing director of Molson Coors, will be giving evidence on behalf of his company.
JWT, BJL, AKQA and Beattie McGuinness Bungay will also make an appearance.
The committee will be particularly interested to question Halewood after it received evidence at last week's hearing that indicated that the company had tried to sign up Coleen Rooney as a brand ambassador for its Lambrini drink.
Using Rooney would have contravened the rules governing alcohol advertising as she is younger than 25. The committee also expressed concern that Lambrini sponsors Coleen's Real Women show.
Graham Oak, the marketing director of Halewood International, said: ‘As well as addressing historic issues relating to our brands we will be keen to impress upon the committee the fact that we have evolved the positioning of a number of our brands including Lambrini and Sidekick in light of changing regulation and an evolving social climate over the past two years.'
