Clark struggles with facts when she's under pressure

"With Helen Clark's latest gaffe on how fast student loans grow she looks increasingly accident prone," said Roger Sowry.

"Before the campaign was even under way she was apologising to a surgeon because she accused him of doing something he hadn't done.

"Next thing she's promised 3% unemployment by the end of the term of the next Government, and then had to retract it when Michael Cullen heard about it.

"And let us not forget her flip-flops on Party accommodations. When she thought she didn't need the Greens she was highly moralistic about the arrangements others had made. When the tide turned she quick as a flash gave her Coromandel candidate the shove.

"It just shows she isn't very good when under pressure to perform," Mr Sowry said.
