Caveat: I’m never entirely convinced by political party charts, here or in the USA, which may be a problem of iffy dates. But for what it’s worth.
Labour Party, 27 February 1900 has a Mutable T Square of Pluto in Gemini opposition Uranus Jupiter square a Pisces Sun; with Neptune in Gemini square Mercury in Pisces. Last year’s tr Neptune square tr Saturn was in hard aspect to the Jupiter Uranus and Sun as muddles and mayhem sank Labour down the polls. This year tr Neptune continues to undermine Pluto with tr Saturn opposition Neptune and square Mercury, throughout the year, so not much joy there. Solar Arc Sun opposes the Labour Party Saturn in 2018; followed by Solar Arc Mars conjunct Neptune – all of which is bad news right through into 2019. There is a Saturn Return in 2018/19 which might be a wake-up call to get sensible and practical.
Jeremy Corbyn’s relationship chart with Labour 1900 looks on edge through this February with tr Uranus conjunct the composite Sun. Since this hardly looks like a split; it’ll wait till 2018/19 as tr Pluto squares the composite Sun and trines Uranus to cause more obvious upsets; with 2019 looking highly aggravated between them. He won’t be easy to dislodge with a composite Mars square Pluto so any separation will cause great bitterness and hostility.
Liberal Democrats: 3 March 1988, or the original Liberals, 6 June 1859. The 1988 chart is sagging through 2017 with tr Neptune conjunct the Pisces Sun, but having better luck in 2018 as tr Uranus is conjunct the Jupiter. The Liberal 1859 chart has a 15 degree Gemini Sun so much the same with tr Neptune square the Sun in the immediate future, though also better luck showing in 2018/2019.
UKIP: 3 September 1993 is in meltdown with tr Pluto conjunct their Uranus Neptune conjunction in 2017/18.
Conservative Party: 12 November 1867 has tr Pluto sextile the Scorpio Sun in 2017/18 which is generally positive progress; with a confident boost in 2018 from tr Uranus sextile Jupiter. But beginning to hit heavy seas by 2019/20 with tr Pluto sextile the Sun/Saturn midpoint, followed in 2021 by tr Pluto sextile Saturn which looks bleak.
Theresa May’s relationship with the Tories is bumping along uncertainly through this year with tr Uranus square the composite Neptune, Mars and Uranus from next month onwards; with more major upheavals in 2018 as tr Uranus opposes the composite Sun; and hitting confusion/devastation also in 2018 with tr Pluto conjunct the composite Neptune, moving on to conjunct Mars by 2020, which looks highly aggravated and stuck.
