Liberal MP Dave Sharma has told voters they risk losing a moderate voice inside the party if he is ousted from the Sydney seat of Wentworth, one of several electorates targeted by prominent independents.

Mr Sharma is facing a sizeable threat from Allegra Spender, who used the same debate to promise action on climate change, a federal anti-corruption commission and a reshaping of the economy.
