Roundup: Britain's new Labour Party leader launches mission to No. 10

With over 11,000 participants, Britain's Labour Party Conference is one of the biggest events in Europe's political calendar.

As well as over 500 "fringe" meetings over four days, all eyes will focus on what is said in the main conference hall.

As a curtain raiser to today's big conference speech by Jeremy Corbyn, John McDonnell addressed the conference with a rousing speech that earned him a standing ovation.

He mapped out his - and Corbyn's - road map to march austerity out of Britain, cheered as he gave notice to multi-nationals they would have to pay their fair share of taxes, getting Britain back to work with construction projects and housebuilding, ending what are seen as heartless welfare reforms which have seen the poor become poorer, while the rich become richer.

McDonnell pleaded with parliamentary colleagues who have snubbed Corbyn to return and help the party regain power. To voters in Scotland who abandoned Labour in their tens of thousands to vote for the nationalists, he told them to "come home" adding Labour was now the only anti-austerity party in the country.

Tuesday's national media trailed the eagerly awaited Corbyn speech. The loyal Daily Mirror said Corbyn will make a patriotic conference speech to restore his reputation. "Call me Mr Nice" headlined the Independent, trailing the speech.

The Sun, one of the most anti-Corbyn newspapers, used the announcement about the "red" planet Mars, in its take on the Labour conference.

The Red Planet, screamed its banner headline, with sub-headings: Labour War on Capitalism, State Control and big tax grabs, On a mission to another world.

The Sun commentary on McDonnell's speech said: "hard left Labour unveiled a catastrophic tax-and-spend economic blueprint guaranteed to bankrupt Britain. As scientists revealed evidence of water on red planet Mars, Shadow Chancellor John McDonnell told Jeremy Corbyn's party 'Another world is possible'." Endit
