DANNY Alexander, the re-elected Lib-Dem MP for Inverness, Nairn, Badenoch and Strathspey, played a pivotal role during five days of intense negotiations when the May General Election produced a hung parliament.
Mr Alexander was part of his party's negotiating team which drew up the document for the new coalition government with the Conservative party.
The 38-year-old was appointed the new Scottish Secretary making him the youngest member of the cabinet headed by Conservative Prime Minister David Cameron with Nick Clegg as Deputy Prime Minister.
Mr Alexander said: "This is a coalition in which the Lib-Dems are playing a full role.
"It is based on two things. Firstly, it is a desire to see politics done differently in this country.
"As I knocked on so many doors in Inverness, people said they wanted to see politicians working together to sort out problems.
"Secondly, I think people who voted Lib-Dem will look at the agreement that I led negotiations on and will see a programme which delivers a huge swathe of what we were promising in the election."
This included a referendum on the voting system and delivering greater fairness through measures such as raising the threshold on income tax.
Mr Alexander was later promoted to Chief Secretary of the Treasury following the resignation of David Laws.
