Former NSW premier Gladys Berejiklian has faced the anti-corruption watchdog today after a dramatic first day of evidence last week.

Ms Berejiklian has today told the corruption watchdog she believed her secret MP boyfriend's requests for her to use a private phone or encrypted apps reflected a concern for privacy. 

On Friday the Independent Commission Against Corruption (ICAC) heard numerous tapped calls between Ms Berejiklian and her former boyfriend and Wagga Wagga MP Daryl Maguire.

The calls gave insight into the pair's relationship and exposed how Mr Maguire would rant to Ms Berejiklian about not getting enough money for his electorate.
