Farage will grow and grow and grow as long both major parties in the UK do not deal with immigration. This is legal immigration. The figures are not discussed
All Farage will need to do at the next election will be to go on about the migration figures. Labour are toast unless they can show a clear plan about migration figures. Reversing most of what the Conservatives did since 2019 would be a good start
I don't agree @bombastix .
I can't remember if it was YouGov or another polling outfit which produced a poll before the GE on what people in the UK are most concerned about. Immigration was not at the top of the list. That is why, despite everything, Reform only got 5 seats. There is still only a limited cohort in the UK which buys into Farage's rhetoric. Those who don't will never be swayed by his xenophobia.
The only way Reform will secure a significant number of seats is if PR is introduced. Also remember, some of its core voters will have dropped off their perches by 2029. Finally, if there is a real threat from Reform come 2029, I truly believe that the rest of the non-rabidly right wing electorate, including One Nation Tories, will vote tactically to keep Farage in his box.
