BS for one and all...
"Last year the UK government greenlit £92m on pondering if it could make its very own Brexit Satellite (BS)..."
I would contend that the UK government is an absolute master at producing BS...
The UK Space Agency has flung open the doors on a mighty £2m fund aimed imbuing Blighty with spaceflight capabilities. The agency breathlessly speculated this morning that existing airports could develop the capability for spaceplanes to take off and deploy satellites, or send vehicles on sub-orbital jaunts. We, however, …
I'm going to be pedantic, and point out that most of the propellant* in a rocket launch goes towards accelerating the vehicle sideways, rather than into lifting it up.
The only reason rockets go up first and then turn sideways is because it's easier to go fast if you go up high where there's less atmospheric drag.
On the Moon (as an example), as long as there's no mountains or anything in front of you, you could start your rocket flying sideways right away, and save a bit of delta-V otherwise lost to fighting gravity.
* approx 7-8 times more
Maybe my favourite XKCD: https://what-if.xkcd.com/58/ "Space isn't like this:", "Space is like this:".
(Well, that or https://xkcd.com/979/)

"most of the propellant* in a rocket launch goes towards accelerating the vehicle sideways, rather than into lifting it up.".
A bit about that claim.
Standing say on the equator, we move sideways at the speed of 40.000km/24h which is 1666 km/h and that is why it's more feasible to launch closer to the equator. The rocket goes straight up in relation to it self, shortest route through the atmosphere.
The only way for us to see it go straight up is if it was launched from one of the poles.
And meanwhile we run around the sun at 107.000 km/h which means that some, in my opinion, rather fantastic calculations are needed to take a short shot to Mars, and still that mathematics is old stuff.
The UK hold the Honour of being the only nation to develop satelite launch capability the give up .....
Still Aus are re-opening woomera, so we could probably jump in on that....
and R4 is currently suspended from the ceiling on Level 0 in the Science Museum London

so with £2m we might be able to get that in working order and into the air....

I dont know about that, have you ever tried to walk out of a museum with one of the exhibits? The staff tend to get really really angry, I'm not even sure they'd let you walk out with the rocket even if you gave them the £2m. Selfish buggers, only thinking about themselves...

">Remember when the UK launched its own satellite on its own rocket?<
The last surviving rocket of that type is on display at the Space Centre in Leicester"
The surviving Black Arrow satellite launcher is at the Science Museum in London - they used to have it on display at more-or-less ground level, but it's hung up high now and you can't examine it closely which I think is a shame.
The surviving Black Knight sounding rockets - the ancestor to Black Arrow - are at the Royal Museum in Edinburgh and the World Museum in Liverpool.
The Leicester Space Centre has a couple of big ballistic missiles: a US Thor and a British Blue Streak. Neither use the British designed (developed from WWII German tech) hydrogen peroxide/kerosene engines which powered the Black Knight and Black Arrow, although the Thor missile was the basis of the Thor and Delta satellite launchers, and Blue Streak was used as the first stage of the Europa launcher of the European Launcher Development Organisation (ELDO). Blue Streak turned out reliable, but Europa never managed a fully successful launch and ELDO was wound up.
From what I've just read, ELDO was wound up in part because the UK government decided to go for Black Arrow and pulled out of ELDO. After ELDO was wound up, the ESA was set up to develop a new launcher and what with one thing and another we got the Ariane 1 rocket which was largely a French project, with the UK being a marginal player. Well done the ESA - but a real shame that our politicians didn't have the imagination to stick with the space launch business back then.
One would think the wallet cracking would be aimed at the Sabre project to support it more and to keep it in house. The latest tests were done in the states and I am sure the test data will have been recorded, copied and perused for subsequent use.
It's not as if the UK gov' won't spend money, just not on really useful things.
£2m wont get public sector space travel out of a committee room but then thats probably the best place for it to stop. Let the private companies push this. If there is money to be made they can do it, otherwise there is plenty to waste money on. These are politicians, they could probably blow the £2m on a lunch.
So, I did the arithmetic and found that using the rates NASA will be paying to SpaceX in 2020-2024 and today's exchange rate, two million English pounds will get about 55kg (41.7 of them pressurized) to the ISS. I also checked -- Neither Donald Trump nor Theresa May weigh less than 55 kilos although Ms May is only 5kg over. I put all that in a post nicely laid out in case anyone wanted to check the arithmetic, pressed Preview, and the Register/Opera/the CIA/Google/Microsoft/Huawei/Julian Assange or something ate my attempted post.
BTW, on your rather tight budget, I'd look into sharing a Rocket Lab launch from New Zealand. They are quoting $5.7M for a launch. More that you folks have of course. But maybe Rocket Lab will dicker. Or maybe you can take up a collection to raise the difference. Do any of your politicians play the accordion well enough to hustle some cash on a street corner?
I reckon it'd be better to give the two million to a contracter - Copenhagen sub-orbitals. They'd love to have the cash, and they need test payloads for their program to send an astronaut up one day.. Heck, could even forget about the parachutes to save a little weight, if the test payload (Farage, May, hated politico of choice.) is a tad too heavy.
