Denis Healey and Geoffrey Howe were both "intellectually and politically formidable" parliamentary giants who will be "greatly missed", John Bercow has said.
The Speaker led Commons tributes at the start of Monday's business.
The deaths of former Labour chancellor Lord Healey and former Tory chancellor Lord Howe were announced earlier this month while MPs were away from Parliament during the conference recess.
Mr Bercow said: "By any yardstick and I think, without any doubt, both of those individuals were quite outstanding parliamentarians, people who served their constituents, their parties and their country with unwavering loyalty and distinction.
"Intellectually and politically formidable, they will be greatly missed.
"They had impressive hinterlands both of them and I hope the House will join me in extending condolences to both of their families and friends."
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
