Former Bermondsey & Old Southwark MP Simon Hughes has been knighted in the Queen's birthday honours list.
The Liberal Democrat, who was defeated by Labour's Neil Coyle at the general election last month, is thought to have declined a seat in the House of Lords.
Hughes served in Parliament for more than three decades, latterly as minister of state for justice in the coalition government.
He said: "This is a great surprise and it is very humbling to be in the company of such clearly worthy individuals.
"I just want to thank the people of Bermondsey and Southwark. They put their trust in me as their member of parliament for more than 32 years and for that I am truly grateful.
"This honour is a testament to the hard work of so many different people and belongs as much to them as to me."
