Election update, 23 April: Economy, economy, economy

Chancellor George Osborne was on the Today programme this morning and the Institute of Fiscal studies is briefing the media today on its analysis of the budget plans in each manifesto.  So we expect much tax and spending news today - from all main parties -  and we've published a briefing on common claims.

Onto the front pages. The Telegraph leads with the impact of a Labour-SNP coalition on family finances. It reports that George Osborne has pointed to Treasury analysis suggesting families will be £350 worse off.

The Express reports on EU regulations which it says could push up the cost of mortgages.

The Daily Mail leads with results of an Ipsos Mori poll, with a focus on views on immigration.

The Guardian's front page focuses on the European Union's response to the crisis of migrants dying at sea in the Mediterranean, saying that most migrants will be sent back. They also feature prominently a comment article which suggests that Guardian reporters are being shut out of the Conservative election campaign trail.

And the Independent leads with a report on a High Court ruling that the government should publish diaries of ministerial appointments and meetings for the public.

In other political news today the Times reports that Boris Johnson is interested in the leadership of the Conservative Party, reportedly saying it would be 'wonderful' to be seen as a contender.
