It has been red tory v. blue tory since Blair took leadership in '93/'94.
It is more of less the same as the US (where it was red v blue republicans for a few decades and is now Republicans calling themselves 'Democrats' v. Christian Nationalist Fascists).
It is the natural continuation of Reaganite/Thatcherite neo-liberal capitalist ideology.
The outcome for the UK will be a lurch right as the poor vote for parties (Reform) who have used the immigration (that has caused serious legitimate problems for poor communities that simply can't afford to support the huge number of asylum seekers that have been dumped upon them) and other cultural issues of various legitimacy (imvho) that poor people have been coerced into finding important, as wedge issues.
Edit - obviously this lurch to the right is the opposite of what should happen but here we go. It is what fossil-fuel powered capitalists prefer to socialism and an egalitarian society any day.
Yes let's see. I expect the media - billionaire owned on one hand, bbc on the other - will do the kind of job on him they did when he was leader of the labour party. He will become mired in claims of antisemitism (whatever that means these days), and whatever else they can throw at him and it won't go anywhere.
Capital drives the UK and capital does not want socialism. The media is in significant part crowd control.
