That's it from the Siambr, on the day we learned what was going on behind the scenes with the Welsh Conservatives.

Senedd Live returns on Tuesday 3 July.

Education Secretary Kirsty Williams says the Welsh Baccalaureate "allows learners to develop their knowledge and understanding of society", and says Mr Hamilton has "no evidence" of propaganda.

The topic chosen by Neil Hamilton (Mid and West Wales), external for the Short Debate is "The Welsh Baccalaureate: education or indoctrination?".

He says Wales' education system is being used as a tool of propaganda.

Neil Hamilton claims that parts of the Welsh Baccalaureate on topics like poverty and famine are being taught from a "centre-left disposition".

The motion of no confidence against the Conservative Welsh Secretary Alun Cairns fails to pass as it did not have the support of Labour.

There were nine for, no abstentions, and 40 against.

Plaid Cymru tabled the motion after the UK government failed to support plans for the Swansea Bay Tidal Lagoon.

The motion, even if it had passed, would have been symbolic. AMs cannot remove Mr Cairns, who is not a member of the assembly.

Mr Cairns has said the tidal lagoon "did not meet the threshold for taxpayer value" despite months of work by officials.

Health Secretary Vaughan Gething emphasises that the Welsh Government is awaiting advice from the Joint Committee on Vaccination and Immunisation on whether to extend the HPV vaccination programme to adolescent boys.

The topic of the second Plaid Cymru debate is head and neck cancers.

Rhun ap Iorwerth (Ynys Môn), external proposes that the assembly:

"1.Notes the increase in incidence of head and neck cancers among men.

"2. Notes the evidence of the effectiveness of HPV vaccination in protecting against these cancers.

"3. Calls on the Welsh Government to extend its HPV vaccination programme to all adolescent boys."

Economy Secretary Ken Skates describes Simon Thomas' document as a "superb research report". He moves the Welsh Government amendment to delete points 2 and 3 in the Plaid Cymru motion and replace with:

"Notes the Welsh Government’s commitment through the new Economic Action Plan to decarbonise traditional models of business, public services and infrastructure in Wales and shift towards a low-carbon future in a way that can support our economy to diversify and grow.

"Notes the Welsh Government’s work to decarbonise the Welsh transport network, including the recent commitment to a 25 per cent reduction in emissions across the Wales and Borders rail network by 2023.

"Notes that work to decarbonise the Welsh transport system must be broad based, with the need for creative research and development in alternative infrastructure solutions and across a range of innovative fuels and traction systems, including hydrogen."

Michelle Brown says UKIP also support the Plaid Cymru motion, adding at the end of the motion a call "on the Welsh Government and the UK Government to ensure that any forms of alternative energy that they explore meet the tests of affordability, which include not placing an excessive burden on taxpayers".

On behalf of the Conservatives, Russell George expresses "support for the objectives" in the Plaid Cymru motion, and they intend to "strengthen the motion" by further noting:

"a) the potential of hydrogen as an alternative form of fuel;

"b) the importance of hydrogen fuel to the diversification of our energy portfolio;

"c) the important distinction between green and brown hydrogen fuel;

"d) that green hydrogen fuel is only viable as a by-product of surplus electricity generation, and therefore its limitations should be recognised; and

"e) that improvements to Wales’s grid infrastructure are required by the Welsh Government in order to ensure that both electricity and hydrogen can be utilised as green alternatives to fossil fuels."

Plaid Cymru has chosen to use its hour by holding two 30-minute debates.

The first is on hydrogen energy, following publication of the report, 'The Potential of Hydrogen in the Decarbonisation of Transport in Wales, external', by Simon Thomas.

Plaid Cymru calls on the Welsh Government "to hold discussions with businesses, researchers and bodies about holding a key event to convey Wales's ambition in relation to the hydrogen economy to a worldwide audience and to trigger the development of a comprehensive hydrogen economy strategy."

Petitions Committee chair David J. Rowlands (South Wales East), external explains the committee reached the following four conclusions.

1. "It is clear that the Welsh Government does not anticipate, and would not welcome, future applications for further opencast coal extraction in Wales. The changes proposed in Planning Policy Wales: Edition 10 would appear to make further new opencast coal mining developments highly unlikely in the future.
2. "Proposed changes to planning policy make it likely that any future planning applications for opencast coal mining would be rejected through a local planning process or “called-in”. We support this approach.
3. "National planning policy should ensure that suitable financial provision for site restoration is paid or guaranteed by those responsible for any future opencast mining developments. The effectiveness of planning policy in achieving this should be kept under close review by the Welsh Government and strengthened if necessary.
4. "We encourage the petitioners, local communities and others with an interest in this issue to submit their views to the public consultation on Draft Planning Policy Wales: Edition 10 prior to the closing date of 18 May 2018."

The next debate is on the Petitions Committee' consideration of two petitions relating to opencast mining developments in Wales.

Both petitions focused upon national planning policy and the approach adopted by the Welsh Government.

The first petition calls upon the assembly "to urge the Welsh Government to make the MTAN Guidance Notes, notably those relating to a 500 metre buffer zone around opencast workings, mandatory in planning law for Wales."

The second petition calls upon the assembly to "urge the Welsh Government to call in all opencast mining planning applications over 10 years duration or over 350 hectares in size because the implications of these developments are far reaching and long standing with effects beyond the immediate locality".

Several AMs speak about problems with the current system of leasehold tenure.

Cabinet Secretary for Local Government and Public Services Alun Davies says the Welsh Government will abstain in the vote because "the government is moving to take the actions we are able to".

The motion is agreed without objection.

The next debate is on a Member's Legislative Proposal, on leasehold residential houses.

Mick Antoniw (Pontypridd), external proposes the assembly:

1. Notes a proposal for a Bill to:

a) abolish the building of leasehold residential houses in Wales; and

b) improve consumer awareness of the implications of leasehold tenure.

2. Notes that the purpose of the Bill would be to:

a) place a duty on local authorities in Wales to reject all planning applications for leasehold residential housing developments; and

b) place a duty on sales and management agents to provide potential purchasers of existing leasehold properties with information on the implications of leasehold contracts.

His proposal is supported by:

Jane Hutt (Vale of Glamorgan), externalJenny Rathbone (Cardiff Central), externalMike Hedges (Swansea East), externalVikki Howells (Cynon Valley), external

The vote on the no confidence motion will be held at the end of plenary.

For the Plaid Cymru motion to pass a majority of AMs would be needed. Labour has 29 of the 60 seats in the Senedd.

An alternative amendment tabled by the Welsh Government criticises Mr Cairns but does not go as far as Plaid Cymru.

It says instead that the assembly "regrets the secretary of state for Wales' failure to stand up for Wales and to support the need for greater UK government investment in major infrastructure projects in Wales".

Mark Drakeford explains why the Welsh Government will not support the Plaid Cymru motion.

"I do not believe we set up the National Assembly for Wales to be an outpost of gesture politics", he says.

Finance Secretary Mark Drakeford says "this is a government with form when it comes to saying no to Wales."

Referring to Paul Davies's claim that the fiscal framework was an achievement by Alun Cairns, Mr Drakeford says Alun Cairns wasn't even in the meetings.

'I'm sure he was there in spirit,' says Conservative Nick Ramsay.

Plaid Cymru leader Leanne Wood says “railways not electrified, bridges renamed in the name of the colonial prince, the tidal lagoon scrapped, that is what is being delivered by the secretary of state in Wales.

“He is Westminster’s voice in Wales and not Wales’ voice in Westminster."

UKIP's Caroline Jones says the UK government has shown "utter contempt for my region" but blames Prime Minister Theresa May and Business and Energy Secretary Greg Clark.

She describes Alun Cairns as a "messenger", adding he needs to be "less of a yes-man".

She says UKIP will support the Welsh Government amendment.
