Bumped from comments below:

Thanks again for keeping an eye on this, Owl.

Your scanned piece from the Sunday Times can be picked up on-line – where the bit we can read tells us that Barker “is set to appear before the Commons foreign affairs committee this week to discuss sanctions. He is expected to face questions about his work for EN+ so far.”

The same article refers to Barker’s lack of interest in the second chamber:

“Former energy minister Lord Barker is stepping away from the House of Lords to focus on his role as chairman of Oleg Deripaska’s aluminium empire, having helped it to avoid American sanctions against Russia. Greg Barker is taking a leave of absence from the upper house after being appointed executive chairman of EN+ this month. He has not voted since February 11, when he told the Lords of his plans.”

Back in August 2016, the Sun considered two of the resigning PM’s choices for gongs:

“TWO of David Cameron’s cronies have attacked criticism of his decision to shower aides and allies with honours. Hugo Swire, who was given a knighthood on Thursday, and Greg Barker who was made a Lord last year hit back at Mr Cameron’s ex-guru Steve Hilton who branded the resignation list “corruption” for including Tory donors.”

The Daily Mail ran a piece back in July 2014 lambasting the Tories for cosying up to Russian money – and it began with an auction:

“As bidding passed the £100,000 mark, guests at this year’s Conservative Summer Party broke into spontaneous applause. For sale was what auctioneer Hugo Swire, a Foreign Office minister and former director of Sotheby’s, billed as a ‘once-in-a-lifetime’ experience: the chance to play a tennis match with both David Cameron and Boris Johnson.”

The £160,000 prize was famously won by a Russian oligarch’s wife:

What is clear, though, is not only that the Conservative Party has seriously compromised itself in taking Russian money (it was the Labour Party which was lambasted for doing so from the 1920s…) – but the extent to which lobbying on behalf of Russian business (aka political) interests is happening at the heart of Westminster – as reported last year by intelligenceonline.com:

It will be interesting, then, when Barker gives oral evidence on “Global Britain: the future of UK sanctions policy” to the Commons foreign affairs committee this Wednesday:

Keep at it, Owl!
