Bob Seely MP said: "I supported Prime Minister Boris Johnson in the recent vote of confidence, following a renewed commitment to look at the Isle of Wight council's funding settlement. Since then, we’ve seen more controversies and more ethical questions.
"Talking with Islanders, it’s clear that Boris - despite his past strengths - is becoming a distraction to governing Britain.
"I am very concerned that important debates and important issues - on the Island and nationally - are being drowned out by the incessant noise from Downing Street. We need to be focused on getting inflation down, supporting people through the cost of living crisis, and growing the economy. On Island issues, I need ministers in place and focused on delivering for Islanders.
"If there is another confidence vote in the Prime Minister, I will not be supporting Boris. We need a change of Prime Minister. I am sorry that it has come to this point, but it is now in our national interest that this happens soon, as I suspect it will."
