David Cameron hits out at Leave claims in Brexit vote

The rival EU referendum camps have clashed over the economy, after David Cameron said a British exit would “put a bomb” under the UK’s prospects.

The prime minister accused the Leave campaign of an “undemocratic and reckless” failure to explain to voters how they see Britain’s economic future in the case of a Brexit vote in the June 23 referendum.

Boris Johnson said it was a “delusion” to think Britain could boost its prosperity by “bartering away our freedom and democracy”.

He warned of a “triple whammy” of economic woe if the UK remains in the EU, claiming that Brussels was waiting until the referendum is out of the way to seek an increase in budget contributions as well as extra cash to fill a £20bn (€25.5bn) black hole in unpaid bills.

Mr Cameron joined figures from Labour, the Lib Dems, and Greens to launch a dossier detailing 23 trade models which they claimed had been espoused at various times by Leave campaigners — each of which they said would have “a profound and damaging effect on our economy”.

They said Leave had made unfunded spending commitments that would create a £153.6bn black hole in the public finances.

Mr Cameron said he was “proud” to stand alongside Labour’s Harriet Harman, Lib Dem leader Tim Farron, and Green leader Natalie Bennett in “an unprecedented show of cross-party unity” in support of continued membership of the EU.
