Liberal Party branch members and sitting MPs have privately urged Dave Sharma to oust Tony Abbott from Parliament, as consensus grows in Canberra that the former prime minister needs to leave politics to let the Coalition heal from an expected election loss.

But Mr Sharma - who lost last month's byelection in the neighbouring electorate of Wentworth to independent Kerryn Phelps - rebuffed the advances and is focused on recontesting the seat next year.

Mr Sharma confirmed multiple Liberal Party figures had urged him to run in Warringah, a prized seat on Sydney's northern beaches held by Mr Abbott since 1994.

"I've never considered it as anything more than a ridiculous suggestion," Mr Sharma told Fairfax Media.
