New Delhi, June 30 -- Prince William and Kate Middleton face mounting tension. King Charles is welcoming Harry and Meghan back to Britain. This marks Meghan's first UK visit in nearly 4 years. According to Heat magazine, it doesn't go well with the future king and his wife.

An insider has told Heat that Kate feels "stressed and conflicted" about the visit. The source says Kate remains forgiving but cannot forget past hurts. Meghan's involvement reportedly complicates things "worlds more" for Kate. She feels more anxious due to the 'homecoming', according to the source.

The insider suggests that Kate would be more likely to welcome Harry alone. It is Meghan's presence that allegedly changes the dynamic entirely.
