Speaking on the BBC Wales Election 2019 programme, Chris Wilkins -who worked as an adviser for Theresa May when she was Prime Minister - said talks had already taken place in Whitehall about “machinery of government changes”.
He said: “They want to do things differently. I’m speculating here, but I wonder if they will think about a minister for the union rather than separate secretaries of state."
Owen Peregrine, the assistant manager at the leisure centre in Newbridge where the Islwyn count is taking place is having an active night.
So far he has walked almost 10 miles.
“I’ll probably do 20 by the end of tonight,” he said.
Former Welsh Conservative assembly leader, Andrew RT Davies said: “It’s still very early days but this is pointing to a very good night for Boris Johnson and the Conservatives.
"People across the country have stood up and told their politicians that democracy should be respected and have also emphatically rejected the hard-left socialist dogma of Jeremy Corbyn.
"The prime minister deserves a great deal of credit for leading such a strong and powerful campaign, which has clearly taken the Conservative message into areas of the country we’ve never reached before."

Some Welsh MPs are not seeking re-election, meaning whichever party wins in six Welsh constituencies, there will be a new MP.
Those standing down are:
Party representatives at the Vale of Clwyd count are keeping a close eye on the verification process at the count there.
Welsh Liberal Democrat Baroness Randerson, said: “I find the exit poll obviously disappointing.
“When we’ve been canvassing, it seemed at times like an unpopularity contest between Boris Johnson and Jeremy Corbyn.”
Russell George, Conservative AM for Montgomeryshire, is at the count in at the Royal Welsh Showground near Builth Wells.
"I am a little bit cautious but so far it does look very very good.”
The Conservatives lost Brecon and Radnorshire to the Liberal Democrats during a by-election during the summer.

Tory sources in the Vale of Clwyd constituency are confident.
They've said the local campaign has been run "like clockwork", Jeremy Corbyn has been unpopular in the area, and people have wanted to see Brexit done.
Things could be on a knife edge between Labour, the Conservatives and Plaid Cymru in the Ynys Mon constituency, a Labour official is telling BBC Wales.
Plaid Cymru's Hywel Williams has arrived at the count in Arfon.
His majority in 2017 was 92. Labour are hopeful of taking the seat but Plaid Cymru say they’re quietly confident.
Plenty of crosses into the box at the Cardiff City Stadium tonight... but not the kind you would see from Neil Harris's team.
The stadium in the south west of Cardiff is hosting the counts for the Cardiff West and Cardiff North constituencies this evening.
Boxes have also arrived in Newbridge for the Islwyn count.
Islwyn had one of the lowest turnouts in Wales in the last general election at 64.2%, but there are suggestions they might beating that figure this time.
The boxes are slower to arrive in at the Royal Welsh Showground in Llanelwedd near Builth Wells, the venue of the count for Brecon and Radnorshire.
The seat is the largest geographical constituency in Wales.
According to the exit poll, it might be worth keeping an eye on Wrexham, Vale of Clwyd, Delyn, Bridgend, Clwyd South and Alyn and Deeside tonight.

Labour’s Shadow Welsh Secretary Christina Rees said if the exit poll was correct it would “be a bad night for us”.
She said it was “always going to be very challenging in difficult weather for us to get to see and have as many conversations as we could, but we’ve certainly run a very good campaign in Wales”.
Ms Rees said a pre-election poll had predicted Labour losing nine seats in Wales, but “I think we are in a better position than that today," she said.
Asked about Jeremy Corbyn’s future as leader, Ms Rees gave him her support and said: “Jeremy Corbyn is our leader, he’s led a fantastic campaign. He’s been all over the UK, and he’s been to Wales several times”.
Labour is forecast to take an estimated 191 seats across the UK, down 71, which would be its worst performance at a general election in terms of seats since 1935.
Vaughan Gething, the Welsh Government Labour health minister, said if the exit poll was borne out it would be a "bad night for the Labour party" and "a bad night for the country".
"We did understand that traditional Labour voters, older Labour voters, had a real issue voting Labour in this election," he said.
Paul Davies, the Conservative leader in the Welsh Assembly, told BBC Wales’ Election 2019 programme: “People want to see Brexit delivered and that’s why they have come out to vote for us if this poll is correct."
At the Ceredigion count in Aberaeron, the number of boxes left to count is being projected onto the wall.
Only 48 to go...
Prof Laura McAllister, speaking on the BBC Wales Election 2019 programme, said: “There’s irony here if these results do play out.
"Labour might be looking at having the bulk of its MPs in the south Wales valleys – the part of Wales which is most resistant to Jeremy Corbyn.
"It will be interesting how that plays out for the First Minister, Mark Drakeford, who is himself a supporter of Jeremy Corbyn”.
Welsh Conservative sources have told BBC Wales Political Editor Felicity Evans that “things aren’t looking good” for them in Cardiff North”.
The seat changed from Conservatives to Labour in 2017.
Chris Bryant, the Labour candidate for Rhondda, tweets his reaction to the exit poll:
