Tory backbencher John Bercow has been appointed as the new Commons Speaker after beating nine other candidates.
He has been formally declared Speaker in a ceremony in the Lords chamber. Mr Bercow told MPs it was the "greatest honour" of his political life.
The new Speaker formally took up the role in an "approbation" ceremony - the process of Royal approval. Accompanied by Black Rod, Mr Bercow led MPs from the Commons to the Lords chamber for the ceremony where he was approved in the role.
He will replace Michael Martin, who stepped down after nine years in the job amid the furore over MPs' expenses.
