John Mason said he would not disappoint the people of Glasgow East
The Scottish National Party's newest MP has arrived at the House of Commons for the first time.
John Mason, who took the previously safe Labour seat of Glasgow East last week, met with parliamentary officials.
The 51-year-old was unable to take his oath of allegiance due to the summer recess but wanted to get his office "up and running".
Mr Mason overturned a Labour majority of 13,507 to win his seat by 365 votes with a swing of 22.54%.
The Conservatives came third with 1,639, pushing the Lib Dems into fourth on 915 votes.
Speaking outside the Commons, Mr Mason said: "The people of Glasgow East put their faith in me.
"They had been without the representation they deserve for far too long and they want a change. I will not disappoint them.
"I am determined to be a high profile and high visibility MP, tackling the issues that matter to the people of my constituency."
