I think this is the last airliner built in Britain. BAe RJ85 No. 2394, first flight at Manchester Woodford April 2002, now in service in South Africa.

The very last airliner built in UK was the second RJX airframe, which never went into pax service after the RJX project was cancelled. That aeroplane is now at Manchester Airport viewing park.
