The move comes in advance of May’s anticipated general election and the G8 summit in July.
Redhead will launch a media relations campaign promoting the issues in the parliament’s manifesto to regional and national broadcasters and regional press.
Redhead managing director Sarah Tye said: ‘Anti-Social Behavioural Orders, identity cards and free travel for young people are high on the agenda.’
Redhead will also secure speaking opportunities for the parliament’s 300 members, while 30 official spokespeople will be media trained.
Tye added: ‘We will be promoting the interests of young people to national and local government, the providers of services for young people and other agencies that have an interest in the views and needs of young people.’
The parliament, founded after the 2001 general election and funded by the Department for Education and Skills (DfES), does not have any direct power and members are unpaid.
Development co-ordinator Kate Parish said: ‘Because young people do not have a vote, their views are frequently ignored by politicians; this parliament gives young people a voice.’
The parliament is made up of 11 to 18-year-old representatives from across the UK, is party-independent and issues-based.
It has seven select committees covering international and domestic matters.
Redhead won the business following a three-way pitch and will manage the account until the end of March, when the DfES will announce the result of its current spending review.
