6.30pm: Catherine Murphy TD, who previously used a so-called "throwaway phone" to protect her sources has said she still uses it to communicate with them.
Catherine Murphy said: "I was very conscious of the people who came forward to me, that they expected me to make sure the information was kept confidential…We still have small, cheap phones that we use for specific purposes."
The Sinn Féín leader has said he operates on the assumption that his phone is always being tapped.
Gerry Adams was responding to comments from Social Democrat TD Catherine Murphy, who has said she was warned about phone-tapping at the height of the IBRC scandal.
The TD has said she and an assistant resorted to using called 'burner' phones to speak to contacts giving them information about the state-owned bank.
Gerry Adams has said the IBRC inquiry still hasn't given enough answers - and believes his own phone is also under surveillance: “Well I haven’t had to do it, but I just work on the basis that my phone is tapped, so I just work on that basis, because that is the way the system works.
“More importantly I think that this IBRC issue has not been concluded in a way that has given you, me, other citizens the information we deserve”.
