With 412 Labour MPs, we can expect a significant amount of by elections over the next 5 years where the incumbent Labour MP has gone for whatever reason, and in places where Reform came second. There are over a 100 constituencies where Reform came in a comfortable second from Labour.
As to the Tories, they really need to decide what kind of party they are. Either a Blairite centrist tribute act, or a small 'c' conservative right of centre party that believes in the low tax, small state, controlled immigration model. They can't be both.
Sir Starmer has already scrapped the Rwanda plan and when the weather improves and surge in dinghy crossings is expected. This surge has already been dubbed The Starmada!
What would you consider a significant number? There have been 59 parliamentary by elections in the last 14 years.
Anyone who thinks you can extrapolate by-election results to a full one has either never looked at such results, or is deluding themselves. Actually, they're more likely to be doing both. By-elections are frequently used to give whoever is in power a good kicking. And that's basically what happened with Reform in this election; much of that support will bleed back to the Conservatives, just like the switch between Labour and Conservative in the last one.
The tories turning onto a Blairite centrist tribute act would be like placing two empty mirrors opposite each other

What I meant by that, is with the large numbers of Labour MP's, a significant number of By Elections will be where the incumbent Labour MP has had to stand down for one reason or another. Maybe I could have worded it better, but I wasn't saying that there will be more by elections during this parliament than any other.
Malcolm said that in By Elections it's often the candidate who came second in the General Election that win the By Election, and I just pointed out that Reform came second in over 100 seats, so by that theory they could have more MPs by the next General Election.
As to Reforms prospects, comparing them to UKIP in 2015 is daft. David Cameron had just won a surprising majority ousting the Lib Dems from government which in theory should have allowed him to follow a small 'c' conservative agenda and he announced the EU referendum quickly which completely and utterly neutered UKIP. Todays Tories are a defeated rabble in search of a cause, and the battle for the soul of the party is just beginning. It will be a long time before they get their act together. Get your popcorn out folks!

Meanwhile, the small boats will continue coming across the Channel and these undocumented young men from the Middle East and Africa will be dispersed around the country. They will become a common sight hanging around in groups in parks and town centres. Tales of young girls being approached, followed, propositioned, sexually abused and even raped by these men will spread like wildfire on social media, as much as the media try to pretend it isn't happening.
Farage and Reform, will be the only people talking about this. They will hold Trump style rallies around the country which will attract large numbers of pissed off people and even more people will watch the livestreams. The media will of course dismiss them as racist bigots and will try to ignore these rallies as they did with the Reform rally at the NEC last weekend where 5000 turned up. It was the biggest election event held by any of the political parties. They now have funding and will keep their profile high, so they could well do well at By Elections.
The flip side to this coin is if Labour manage to stop the boats and drastically cut legal immigration, then Reforms reason for being will be as neutered as UKIP's was in 2015. That seems unlikely though...
