The Manchester Airport FAQ page has a section on Domestic to Domestic flight transfer which states:
Transferring from a domestic flight to another domestic flight
On disembarking from the aircraft check the flight information screens for the gate of your onward flight. If no gate information is shown please proceed to the Terminal 3 Departure Lounge. To enter and leave the Terminal 3 Departure lounge please note that you will be required to go through a facial biometric enrolment and reconciliation process. If you don't have your boarding card you will need your confirmation of onward travel to enrol at the biometrics. If you have your boarding card for the next leg of your trip please wait in the lounge until it is time for you to board your next flight. If you do not have a boarding card for your next flight go to the customer service desk in the departure lounge where your handling agent will be able to issue you with your boarding card.
It would therefore seem that you'll have to budget some connection time for the mentioned biometric enrolment and reconciliation process, before accessing the departure lounge at Terminal 3. Whether 35 minutes might be enough transit time is something that you might want to ask the airport directly.
