Former Liberal Democrat deputy leader Sir Malcolm Bruce has taken his seat in the House of Lords.
The ex-Gordon MP, who stood down before the general election after more than 30 years, was officially introduced as Lord Bruce of Bennachie yesterday.
Entering the chamber after Black Rod, he swore an oath of allegiance to the Queen before signing his name.
He was flanked by supporters Lord Wallace of Tankerness and Lord Kirkwood of Kirkhope.
At the end of the brief ceremony, he shook hands with Lords Speaker Baroness D’Souza and Baroness Stowell of Beeston, Leader of the Lords.
Lord Bruce previously told The Press and Journal he opted to include the famous Aberdeenshire landmark in his name because it is visible from everywhere in his old constituency.
It was initially rejected on the grounds the hill is not a “habitation”, but a lengthier form – Baron Bruce of Bennachie of Torphins in the County of Aberdeen – was later accepted.
He will be able to use the shortened form on a day-to-day basis.
Sir Malcolm, who was named in the dissolution honours list, was nominated by then-party leader Nick Clegg.
Asked about choosing a name, he said he could not have Gordon, because there have been dukes of Gordon, or Kintore or Inverurie, which are existing titles.
He added: “Bennachie is characteristic of the constituency. You can see it from everywhere.”
He also revealed that after choosing the name, he climbed the Mither Tap “just to see if I could”.
Upon agreement of a title, Letters Patent, which are issued by the Queen and create a life peerage, are prepared.
Recipients become members when the letters are sealed, at which point they can be introduced to the chamber.
Lord Bruce was deputy leader of the Liberal Democrats from 2014-15.
