He's a VERY blue Tory! Robert Jenrick mocked after it emerges his 'Bobby J' leadership campaign nickname (as plastered across supporters caps) is slang for a SEX ACT

He's been at pains to show off his credentials as a true blue Tory as he runs for the party leadership.

But Robert Jenrick might perhaps have taken the 'true blue' effort too far with his new nickname.

At the Conservative Party Conference supporters have been sporting caps saying 'we want Bobby J', including some who have posed with him.

He was also introduced at one event with the faithful as 'Bobby J, the legal eagle candidate', a reference to his previous career as a solicitor.

However Mail Online can reveal that 'Bobby J' is actually a slang term for a popular sex act.

According to online smut compendium the Urban Dictionary : 'Bobby J is just another slang way of saying ''blowjob''.'

One rival campaign source joked: 'We knew the Jenrick campaign sucked, but with this latest gaffe he's really going down.'

Meanwhile other Tories compared the gaffe to David Davis's Tory leadership campaign in 2005.

He was thrashed by David Cameron after a campaign which saw him pose with women in tight-fitting t-shirts proclaiming 'it's DD for me' - an innuendo on the bra measurement system.

One veteran Tory aide added: 'This is more ''BJ for Me'' than ''DD for me''... it gives a whole new meaning to sucky communications.'

Another Tory source said: 'You have to wonder if team Jenrick have started drinking the kool aid and got a bit drunk on their own publicity.

'This has all the hallmarks of David Davis's botched leadership campaign in 2005.'

Mr Jenrick's camp declined to comment. He has thus far run a strong campaign that has seen him emerge as the frontrunner with Tory MPs and the bookies.

He has run on a promise of tightening up the immigration system.

This morning he warned there 'isnt' a future' for the party unless they campaign to quit the European Convention on Human Rights.

The former immigration minister used a morning campaign rally on the fringes of the Conservative conference in Birmingham to issue a 'leave or die' message.

He channelled ex-prime minister Boris Johnson 's famous 'Get Brexit Done' slogan to call on the party to 'get migration done'.

Mr Jenrick said continued membership of the ECHR was making it 'impossible for us to finish the job we began with Brexit, which is to restore sovereignty to our people and our Parliament'.

He dismissed concerns about the impact of quitting the ECHR on the Good Friday Agreement in Northern Ireland , saying a new British bill of rights could provide a 'pragmatic answer'.

And he also reiterated his call for a 'democratic cap' on the level of legal migration to the UK to bring it down to the tens of thousands per year.
