Tony Abbott has made an awkward appearance on Channel Seven's Sunrise, twice addressing host David Koch as "Chris".

An increasingly tetchy Koch was forced to correct the Prime Minister, who was responding to today's disastrous poll figures.

Answering Koch's first question about the poll, which indicates voters trust him less than opposition leader Bill Shorten, Abbott responded, "Well, Chris ..." before, hastily reverting to "David" and then the matey "Kochie".

Later, after Koch offered him the chance to apologise for the stalled $7 GP co-payment and the planned de-regulation of university fees, Abbott once again gave the appearance of not knowing where he was, calling the veteran presenter and financial commentator "Chris".
