Euan, 29, and Suzanne, 25, were surrounded by their friends and family as they said 'I do' in the Buckinghamshire village of Wotton Underwood.
Euan's parents Tony and Cherie Blair looked on with pride as their eldest son and his girlfriend of more than eight years married in the picturesque setting of All Saints Parish Church.

"It is a very happy day," said Mr Blair. "We are grateful to have such a wonderful daughter-in-law."
Financial analyst Suzanne looked radiant in a cream sleeveless gown which featured intricate lace detailing at the neck.
Fashion commentators also noted that Suzanne's blue heels were a replica of those worn by Sarah Jessica Parker in the Sex and the City movie.

The bright cobalt Manolo Blahnik shoes are available specifically to brides who are keen to observe the saying "something old, something new, something borrowed, something blue".
Among the guests were Euan's sister, Kathryn Blair, who sported a strapless magenta dress, his grandparents Stephanie and Tony Booth and Suzanne's parents Jonathan Ashman and Sedef Altinsoy.
There was some controversy around the fact that Suzanne's stepmother, TV weathergirl Sian Lloyd, did not attend Euan and Suzanne's nuptials.
The newlyweds travelled in a London taxi to their reception
After the ceremony the happy couple hopped into a London taxi, customised with the traditional 'just married' sign and headed to the Blair's £5.75million 17th century mansion for the reception.
Euan and Suzanne got engaged over Christmas 2012, after having bought a house together in Islington, North London earlier in the year.
The newlyweds both have political backgrounds and were introduced by former defence secretary Geoff Hoon when Suzanne was doing work experience with him.
Suzanne's bridemaids all wore pretty light green dresses
She read PPE at Trinity College, Oxford, while Euan graduated with a 2:1 in history from the University of Bristol.
Suzanne, meanwhile, is said to get on very well with her future-in-laws and has previously joined them on family holidays over the years.
