The poll shows a seven-point increase in Reform voters that feel the King is doing a bad job
Reform UK voters have shown the highest levels of dissatisfaction with the King, a new bombshell poll has revealed.
Some 35 per cent of those who backed Reform in the 2024 General Election feel the King is performing inadequately in his role, the latest YouGov Royal Family tracker data shows.
In comparison, just 16 per cent of the country feel the King has done a bad job.
This is despite King Charles reaching his highest-ever approval rating since his accession to the throne almost four years ago, with 68 per cent of Britons thinking he is doing a good job.
Meanwhile, the proportion who believe he is doing badly has fallen by four points, to roughly one in six adults.
Conservative voters are the strongest backers of the monarch, with 90 per cent thinking he is doing a good job, while Lib Dems sit second with 78 per cent.
Labour make the top three with 72 per cent, while 58 per cent of Greens voters are satisfied with the King.
In the spring, Reform voters held the King in the second-most positive light, with 66 per cent. Additionally, just 28 per cent thought the monarch was doing a bad job - a seven-point difference to today.
This summer's polling did show that Britons are now twice as likely to have a positive opinion of the King than negative, suggesting the monarchy continues to be viewed in a positive and stable light, while 64 per cent believe the UK should still have a monarchy.
For the Prince and Princess of Wales, they retain their title as the most popular royals, with between 74 and 76 per cent holding a favourable opinion of them.

At the other end, however, Andrew Mountbatten-Windsor was dealt yet another blow after he plummeted to new depths of unpopularity.
The former Duke of York's positive rating has sunk to a record-low two per cent, while 92 per cent of respondents view him negatively.
Similarly, the Duchess of Sussex has not enjoyed any bounce, sitting with a popularity rating of just 22 per cent, while 65 per cent hold an unfavourable opinion.
The same can't be said for her husband, Prince Harry, who has enjoyed a rare slice of positivity. He has seen his public standing improve notably, with a third of Britons, 33 per cent, now viewing him positively, a six-point climb since May 2025.
This recent bump means he climbs above sisters, Princess Eugenie and Princess Beatrice, who sit at 29 per cent and 30 per cent.
The findings mark a notable shift from earlier polls, in which both sisters outperformed Harry.
