Brexit doesn't matter in this scenario....
Steptoe wins the election with some majority but needs the support of the greens for it to be overwhelming. He immediately decrees that all American forces in UK are 'persona non grata' and have one month to decommission & leave - this also applies to installations jointly operated. Naturally, all nuclear defences, research and supporting infrastructure is to be immediately decommissioned and all means of operating to be rendered useless.
The following month he then announces that all utilities, infrastructure & transport will be taken back into national ownership - including oil & gas production - which will be rapidly scaled back as all profits from production will be used to develop renewables (to keep the greenies on side). At this point, the Wee Krankie (who has 100% of the Jockistani vote) loses her s**t at the loss of jobs and declares a 'hard independence' to keep the oil & gas and refuses to sell any electricity to FUK (Former United Kingdom as it will become known), Steptoe reacts by decommissioning or withdrawing all remaining UK forces, including those at 'Ice Station Kilo' from Jockistan and lodges a court case for access to the oil & gas - which he loses.
Overnight, Russian 'advisors' arrive at all the North Sea rigs by air, simultaneously they also arrive at all the pipeline landing sites, refineries and ports to 'assist' with keeping the oil & gas flowing and therefore the money into FUK, Russian 'advisors' are also seen around LPHQ, Steptoe is seen less & less in Parliament, until there are several incidents in FUK of power generation, refineries and other critical infrastructure being sabotaged, he announces that the Russians have offered to help secure these facilities as they have done in Scotland to ensure continuity of supply... in return, 100% of oil & gas production not required domestically will be sold on the open marked with the profits going to Russia - cue the start of power cuts (blamed on 'sabotage') and the crippling of transport due to fuel shortages, contamination (remember the silicon in petrol incident a few years ago that cost Tesco [mainly] a fair bit to sort out?).
As feeling run higher, the inevitable happens - one of the Russian advisers is killed - this causes the Russians to immediately bring in security for their people, citing the need to ensure their safety, they gradually take over every site where the advisers are located, once this is done - including SAM's in case of 'drone attacks' and the Russians have a stranglehold on FUK's infrastructure, Steptoe Prorogues Parliament and goes into 'talks' with the Russians on restructuring of the FUK...
NATO can't / won't do s**t as the leader of a nation state needs to ask them for help - and they don't want to take on Russia when they were invited in through the front (and back) door.
UK forces consolidate in Wales, RAF Valley is pretty much the only operable airfield and the Royals are stuck in a Holiday Inn just outside Newport....
The horror, a Holiday Inn.
