MPs and peers could be forced to submit to criminal record checks under proposals submitted by a new Labour MP.

In a letter seen by Sky News, Jo White urged the leader of the Commons to examine whether a new committee set up to modernise parliament should force all new members to have checks due to their access to young and vulnerable people.

She suggests in-depth background checks by the Disclosure and Barring Service – commonly known as DBS checks – as the initial stages of introducing MPs to parliament.

Candidates are currently banned from running to be an MP if they have been jailed for more than a year in the UK.

However, there is no requirement for DBS checks, something most other jobs require when applying for positions working with vulnerable people.

Ms White previously submitted an early-day motion on this issue, with cross-party signatures including 13 other Labour MPs supporting her motion.

In her letter to the committee, the Bassetlaw MP writes: “It is a privilege that, as parliamentarians, we can work with local schools, care homes and hospitals, but we must be proactive in preserving this trust.

“Implementing a mandatory check would protect both the people we visit and ourselves. It would be key to maintaining public trust and high workplace standards across the estate and in our constituencies.”

DBS checks are standard practices for GPs, nurses, teachers and other professions. They let potential employers know if a candidate has a criminal record or is banned from working with children or vulnerable adults.

Many local authorities already run DBS checks on elected officials but it’s not standard practice in parliament.

Prospective MPs can stand for election despite having a criminal record or appearing on the child-barred list or adult-barred list unless they have served a prison term over 12 months.

In fact, they do not need to disclose any criminal behaviour to the public prior to becoming a candidate.

The main vetting process before entering the House of Commons is done through political parties, who set their own rules for carrying out any such checks.

None of the Reform UK MPs have signed the early-day motion and leader Nigel Farage said last election there was “no vetting” of candidates.

This has already caused some controversy.

One Reform MP, James McMurdock, was jailed 19 years ago for repeatedly kicking his then girlfriend, according to court documents disclosed by The Times.

The South Basildon and East Thurrock MP attacked her in 2006 while drunk outside a nightclub and spent 21 days in a young offenders’ institution.

He had not publicly disclosed the conviction and described it as a “teenage indiscretion” when asked about the incident last year.

Under new rules, new MPs might have to fully disclose their criminal past.

The creation of a modernisation committee was a Labour manifesto promise and now sits as a cross-party group tasked with reforming House of Commons procedures and improving standards.

The committee said it would not be commenting on submissions until it’s had time to fully consider all options, but is due to publish an initial report early this year.
