Pressure is continuing to ramp up for a Royal Commission into unethical banking behaviour.
The Opposition Leader Bill Shorten wants the government to consider the option while some Coalition and Labor backbenchers think it's the only way of getting to the truth.

Mr Entsch's comments follow similar calls from Nationals senator John Williams and Labor senator Sam Dastyari.
