What's been said

Barack Obama and David Cameron have a joint article in the Washington Post about the close nature of the alliance between the US and the UK. They say: 'with confidence in our cause and faith in each other, we still believe that there is hardly anything we cannot do'

Labour has lots its liberal heritage, argues Patrick Diamond and Michael Kenny in The Guardian. The party has to decide what kind of liberal social democracy the party wants to espouse, they say.

Mary Riddell in the Daily Telegraph suggests that Ed Miliband and Ed Balls have lost the economic argument, but crime and policing could provide them with more of an audience

Inspired by the Charlie and Lola stories, Rachel Sylvester in The Times (£) argues that David Cameron should unite his expert adviser on behaviour and the head of his troubled-families team in No 10 to deal with 'broken Britain' - there could be a political prize in it too
