It’s been a time for swansongs at Westminster.
Most notably, Theresa May is due to field her last prime minister’s questions this afternoon.
Ditto Greg Clark who took what is widely expected to be his final grilling in the House of Commons as Secretary of State for Business, Energy and Industrial Strategy on Tuesday.
The Tunbridge Wells MP is reckoned to have very little chance of holding his seat in the Cabinet as Boris Johnson enters Number 10, given his very public opposition to a no-deal Brexit in recent months.
And Claire Perry, currently on leave from her post as minister of state for energy, on compassionate grounds, has been tipped for the chop too, even though she has been less vocal in public about the perils of leaving the EU without a deal.
So this week could see a big turnover in ministerial jobs, given that Johnson could have a lot of political favours to repay.
What is in little doubt is that the BEIS department is likely to experience big changes over the next fortnight. It may not even survive in its current form.
Liz Truss, currently chief secretary to the Treasury, is tipped to take the top job at the business department if she fails to land her dream job as chancellor.
The former accountant has marked herself out as the keeper of the Thatcherite flame in government so can be expected to have little interest in Clark’s industrial strategy. Once again, it could be all change for energy policy at Westminster.
