Tim Farron's mission: To get Lib Dems 'back in power'

Tim Farron's "mission" as Liberal Democrat leader is to get them "back in power at every level throughout Britain", he has told activists.

In his first big conference speech, Mr Farron said the Lib Dems were now the only "credible" opposition to the Conservatives.

And he invited liberals from across the political spectrum to join the party.

He also mounted his strongest attack yet on David Cameron's "pitiful" response to the refugee crisis.
