Boris Johnson's 'mistress' pictured 'licking salt off woman's breast' at party

Fresh photos have emerged of Boris Johnson’s alleged mistress Jennifer Arcuri partying before she met the future Prime Minister.

At a party in Trondheim, Norway, Ms Arcuri is shown knocking back “booby shots”, apparently licking salt off another partygoer’s breast, before downing a shot of alcohol and giving a thumbs up.

Videos of the boozy bash were posted on Ms Arcuri’s YouTube channel in 2010.

It comes as fresh claims emerged of apparent concerns over grants received by Ms Arcuri for her firm Innotech after she met Mr Johnson in 2012.
