Gordon MP Sir Malcolm Bruce received his knighthood from the Queen last week.
Sir Malcolm was awarded the Knight Bachelor in the Queen’s birthday honour list in June for public and political service.
He was accompanied on his visit to Buckingham Palace by his wife, Rosemary, a former Deeside councillor, and his brother and sister.
Sir Malcolm, who has represented the area since 1983, said: “It was a huge surprise and a privilege to be awarded a knighthood in the Queen’s Birthday Honours in June.
“I have been inundated with letters, cards, texts, tweets, Facebook comments and phone calls and very much appreciate all the kind comments I have received.
“It is very pleasing to be honoured in the Queen’s Diamond Jubilee year, my 30th year in Parliament and the 50th anniversary of the year I joined the Liberal Party.
“The citation is for public and political service and I owe a great deal to the people of Gordon who have elected me to Parliament in seven elections.
“I also hope it reflects my work for the deaf community and international development and that it may help focus attention on these key sectors.
“It was a very special day for my family and me on Wednesday when I was invested at Buckingham Palace.”
