Election 2015: Conservative manifesto explained

David Cameron has said his aim is to guarantee a "good life" for British workers and families, as he launched the Conservatives' election manifesto.

The prime minister said he wanted "to finish the job" of rebuilding Britain on behalf of working people.

He pledged to pass a law to keep minimum wage workers out of tax, to double free childcare to 30 hours a week and to boost "right to buy" home ownership.
