Here's the chart for tomorrow's budget:

The Jupiter-Chiron-Neptune conjunction in Aquarius is on the midpoint of the UK's Venus and Pluto, which are the planets of finance, the economy, assets, and national values, so we can expect a lot of hype, bluff and bluster and a hefty does of Disney fantasy trying to cover up the lameness of it all. The transiting Descendant goes across the UK's Venus reflecting a 'setting sun' in the UK's economic outlook.
On the positive side, there is inspiration and human ingenuity depicted here. It just needs to be applied in an earthy way rather than siphoned off into Public Relations projects and all that hot air emanating from the economic lever-pullers.
The budget takes place following Pluto's stationary-retrograde phase, just as the Sun is trining Pluto between Taurus and Capricorn, which are both earth signs. This aspect reflects a stabilisation, but also an inertia - there's nothing exciting here nor any 'full steam ahead', just a slow, steady plod through fields of mud towards more fertile soil.
The Moon-Venus-Mars conjunction is opposite the UK's Uranus indicating shocks and turbulence, and an attempt to have a galvanising effect in the short-term. It's not worth the disruption, frankly. And it's noteworthy that this triple conjunction is taking place in the final degrees of Pisces. There's a 'last gasp' quality to both Pisces and the final degrees of a Sign. There's a need to let go so that something new can come, but the new is not yet here and the swansong has yet to be fully played out.
All of this happens within the context of Pluto's transit to the UK's Uranus, Ascendant, IC, and Sun. This is a very rare and long-term transit, reflecting deep structural and radical change in the UK at every level: psyche, character, institutions, government, international relations, and more.
