Alun Hugh Cairns MP is a Welsh Conservative politician, who became Secretary of State for Wales on 19 March 2016.
On Monday, MPs will see proposals from The Commons Standards Committee to change their code of conduct - including on the jobs they are allowed to do on top of their work in Parliament.
MPs after weeks of damaging allegations about some MPs apparently working for commercial interests.
But there are concerns this move will do nothing to tackle another potential source of scandal.
" Whilst we welcome the renewed attention on MPs' second jobs and proposals to tighten The Rules governing them, all-party parliamentary groups still provide a backdoor for lobbying, " said Rose Whiffen, of campaign group Transparency International UK.
" APPGs can be used by both foreign governments and private companies to curry favour with those in high office, putting parliamentarians in a precarious situation where their public role may be at odds with their outside interests.
" In order to avoid The Next big lobbying scandal, there should be much greater openness and accountability over how APPGs are run. "
According to Bbc research, an estimated £30. 7m - as published on the APPG register - has been funnelled into the groups since 2017.
APPGs may sound official, but they are, in fact, informal groupings of MPs who share an Interest in a particular topic.
Tom Brake , the former deputy leader of The House of Commons, has asked The Committee to ensure the maximum amount of transparency whenever MPs who sit on these groups are also paid by private companies.
A Liberal Democrat MP for two decades, Mr Brake was a member of a several APPGs himself when he was in Parliament.
He lost his seat in 2019 and now runs The Campaign group Unlock Democracy.
He says: " There are a very large number of APPGs which operate in a way which is perfectly acceptable.
" But there really should not be a scenario where a member of Parliament is part of an APPG that is representing the interests of a particular sector, and who is at the same time receiving funds as an adviser to a company in that field of activity.
" I wrote to the Standards Committee very specifically to look at those areas of concern. "
In the register of members' interests, the Tory MP said that he was paid £15,000 a Year to provide " strategic advice".
The Body signing off ex-ministers' business appointments, ACOBA, gave its approval.
But that approval came with conditions. In a letter to Mr Cairns, The Body 's chairman Lord Pickles says: " For two years, you should not become personally involved in lobbying the UK or Welsh Government on behalf of Veezu Ltd. "
And he adds a definition of what the lobbying restriction means. Mr Cairns " should not engage in communication with government (ministers, civil servants, including special advisers, and other relevant officials) - wherever it takes place - with a view to influencing a government decision, policy or contract".
The Group 's work programme for the Year - Seen by The Bbc - suggests that the APPG's members " build upon The Relationship with Baroness Vere" - a transport Minister - and also pushes for primary legislation on taxi regulation. And it was agreed at the groups AGM to " continue pressuring government to provide urgent financial support for taxi drivers".
Mr Brake said: " It seems to me there is at the very least a case to answer About That member of parliament indulging in paid advocacy. "
A spokesman for Mr Cairns rejected any suggestion of a conflict of Interest . He Said : " Explicit agreement was gained from the Parliamentary Registrar before accepting the nomination from the Labour Chair (of the Taxis APPG).
" In addition, caution is exercised not to contribute to any discussion that could be perceived to have a conflict of Interest . "
Conservative MP Sir Bernard Jenkin , a leading member of the Standards Committee that will propose new APPG Rules next Year , said: " The Principle is that The Public should have the confidence that no-One is getting privileged access to, or influence over, MPs and ministers.
" There is a very strong role for APPGs on particular causes and for strengthening the links between the UK and other countries. We need to strike The Right balance. Transparency is all. "Overseas interests
Conservative MP Bill Wiggin was - from November 2017 until April this Year - a member of the APPG on the Cayman Islands , which exists to " to maintain links with, and develop an understanding of, the Cayman Islands ".
Since 2015, he has been a director of Emerging Asset Management (EAM) Ltd and since 2016 The Business has been running two online investment services - or fund platforms - Based in the Cayman Islands .
The North Herefordshire MP has also extolled the conservation benefits of shooting wildlife, and has received benefits from an organisation involved in countryside sports.
Since 2011, The British Association for Shooting and Conservation has donated A Day 's shooting and an overnight stay multiple times for Mr Wiggin In Country estates in Staffordshire and Derbyshire worth a total of £4,904.
A blanket ban on MPs sitting on APPGs if they are paid by a company, or run a company, in the same sector isn't straightforward.
This operates schools and residential homes for children with behavioural, emotional, social, learning or physical needs, and it is an independent provider of foster care.
But he would fall foul of The Type of ban on APPG advocated by Mr Brake.
" My role with OFG is as Chair of The Independent Safeguarding and Quality Board which scrutinises The Work of OFG and holds them accountable for the safety, wellbeing and progress of The Children in their care. That does not involve political consultancy. "
And He Said his APPG activity should be taken as a whole.
" I Am (also) an officer of the APPG on Adoption. If those children are adopted they are no longer in care and OFG will not receive any revenue so in promoting adoption…it would not be helping OFG.
" Similarly the 1001 Days APPG is all about early intervention to keep children bonded with their birth families and out of the care system.
As Is often the case in Parliament, it is easier to call for reform than deliver it.
