King Charles was forced to cancel a string of engagements after experiencing serious side effects after his cancer treatment.

The 76-year-old monarch reportedly had a scheduled appointment for his ongoing medical care after being diagnosed with cancer.

However, he suffered from some serious side effects that required a short period of observation in the hospital.

The King was reportedly brought back to Clarence House and is now working away as usual. But all public engagements related to him were canceled.

Many described it as a minor bump in the road that’s very much leading in the right direction.

In order to protect and prioritize, he regretfully cancelled all of the planned engagements in Birmingham tomorrow, sources shared.

There was no drama, and he described the trip to the hospital as very brief and connected to his treatment program.

But it’s still a concerning reminder that he’s still undergoing some very serious treatments that do come with some serious side effects. Not a lot of the side effects are planned in these types of conditions, an insider mentioned.
