A book about the case of jailed jockey Christy McGrath is due to be launched in Westminster today as part of a campaign to secure the Irishman's release.
Mr McGrath, from Carrick-on-Suir in Co Tipperary, is serving a life sentence in Britain for a murder he says he did not commit.
Speaking ahead of today's launch, Tipperary TD Seamus Healy said: "We have excellent lawyers and solicitors working on his behalf and we are absolutely adamant and satisfied that an appeal hearing will be got for Christy."
