Birmingham MP Gisela Stuart is mourning the death of her husband, key government advisor and economist Derek Scott.
Mr Scott, originally from Bromsgrove, was Tony Blair’s economic adviser from 1994 to 2003, working in Downing Street after Mr Blair became Prime Minister.
He died aged 65 on Tuesday after being diagnosed with stomach cancer in December.
Ms Stuart (Lab Edgbaston) said: “He was someone who always challenged the received wisdom. If everybody agreed on something, he’d see it as a sign it needed looking at.”
Mr Scott was educated at Liverpool University and the London School of Economics. He worked for Denis Healey, the former Chancellor and Labour deputy leader, and for Jim Callaghan, the former Prime Minister.
As an adviser to Mr Blair in opposition, he helped develop policies leading up to Labour’s historic general election victory in 1997.
On leaving Downing Street he published his memoirs, Off-Whitehall, which were controversial because they exposed the rift between Mr Blair and his Chancellor, Gordon Brown.
Although the conflict between the pair has since been widely reported and discussed, Mr Scott’s account of shouting matches between the two most senior figures in government, and his claim that Mr Brown sometimes refused to disclose information to the Prime Minister, was explosive at the time.
However, his prime concern was with the euro and the book set out the case for Britain remaining outside the single currency.
Later, he was a leading campaigner for a referendum on the Lisbon Treaty, the EU treaty which replaced the proposed EU constitution.
Mr Scott also enjoyed a successful career in the private sector, as Director of European Economics at Barclay’s de Zoete Wedd (BZW), chief economist at Shell UK and international policy adviser at Shell International.
Ms Stuart and Mr Scott had been partners for 10 years. They married 18 months ago.
Mr Scott had briefly been a member of the SDP, the breakaway party formed by senior Labour figures in the 1980s, and stood for Swindon for the party in 1983, coming third.
He attempted to stand for Parliament again in 1997 – this time back in the Labour Party – but his bid to become the candidate for the safe Labour seat of Pontefract in Yorkshire failed when the party picked Yvette Cooper, now the Shadow Home Secretary, as the candidate instead.
After leaving Downing Street he became known – rather like Ms Stuart – as a critic of Gordon Brown, and he was one of only a few Labour figures willing to talk about Mr Brown’s character flaws before the former Chancellor took over as Labour leader in 2007. Again, the comments may have appeared disloyal at the time but others later said the same thing.
The pair also shared concerns about the single currency and the future direction of the European Union.
Mr Scott became vice-chair of Eurosceptic (or “Eurorealist” as some supporters preferred) pressure group Open Europe.
And he chaired a cross-party campaign called “I Want a Referendum” which demanded a public ballot on the Lisbon Treaty.
This was based on the European Constitution, which the Labour government of the day had promised to hold a referendum on. However, once the constitution was repackaged as a treaty, Ministers decided the promise no longer applied.
Ms Stuart had formally helped to draw up the constitution as a member of the European Convention charged with writing it, although she reported that convention chairman former French President Valéry Giscard d’Estaing largely ignored the views of its members.
