The tributes to architect Richard Rogers, who died this weekend aged 88, have been led by fellow Pritzker Architecture Prize-winner Norman Foster.
Foster, who first met Rogers when they were both students, described the architect as a "kindred spirit".
"Richard Rogers was a great pioneering architect of the modern age, socially committed and an influential protagonist for the best of city life ? such a legacy," said Foster.
"I am so deeply saddened by the loss of my oldest and closest friend."

Rogers was one of the world's most renowned architects. In a seven decade-long career he was recognised with the Pritzker Architecture Prize, Royal Gold Medal and American Institute of Architect's Gold Medal. He passed away at his home on Saturday night.
Foster and Rogers had a "unique blend of friendship and collaboration"
Foster and Rogers met while studying at Yale University and went on to establish a studio together when they returned to the UK. The pair would lead the development of high-tech architecture and become two of the world's leading architects.
"Over the time since we met, almost exactly 60 years ago as students at Yale University, Richard has been a kindred spirit," said Foster.
