Matthew Barrett, Conservative Home, posts on those MPs whom he describes as the most "cost-efficient" when considering "staffing costs, travel expenses, office costs, salary, and so on". Barrett highlights the fact that the majority of the top 50 MPs are Conservative.
If cost-efficiency were to be measured by being a member of the "voting fodder brigade", then as far as the Conservative Party is concerned the following have earned merit-marks for never having once rebelled against the government.
Ben Gummer; Guy Opperman; Jonathan Lloyd; Sajid Javid; Conor Burns; Eric Ollerenshaw; Rehmen Chishti; Alok Sharma; Kris Hopkins; Stephen Metcalfe.
