Kovalainen to stay at Caterham for rest of 2012

Heikki Kovalainen has dismissed advice he should quit Caterham as soon as possible.

Fellow Finn Mika Salo, a former Ferrari and Toyota driver, told the broadcaster MTV3 he thinks Kovalainen should jump ship now because Caterham has failed for the third year running to move into the midfield.

But Kovalainen hit back by insisting he will at least see out his contract.

"It is a fact that I have a contract until the end of this year. It’s written on paper," he said in Shanghai.
