The Liberal Democrats claim Wales
would gain an extra £560m a year due to their election pledges on education.
The party has unveiled a £10bn
boost to schools in England in its manifesto.
Education is devolved, so more
spending in England triggers extra cash for the Welsh Government to use as it
sees fit.
Pledging to stop
Brexit if it wins a majority, the party says it would herald a wider
remit for the assembly with powers over policing and prisons.
"The election of a Liberal
Democrat majority government on a clear stop Brexit platform will provide a
democratic mandate to stop this mess, revoke Article 50 and stay in the
EU," the manifesto, launched Wednesday, said.
"We are unashamedly fighting
to stay in the European Union, and we are the strongest party of Remain."
Welsh Lib Dem leader Jane Dodds
said she would urge ministers in Cardiff to spend the extra money promised on schools,
to give children "the best start in life".
Her party colleague Kirsty
Williams is education minister in the Labour-led Welsh Government.
"Our ambitious plans to
reverse cuts to education in England would provide £560m more that the Welsh
Government can spend on our schools and teachers, to ensure we continue to
build an education system fit for the 21st Century," Ms Dodds said.
The Lib Dems say the money would
come from what they claim would be a £50bn boost to public finances by
cancelling Brexit.
BBC Reality Check correspondent
Chris Morris has said the vast majority of forecasts do expect the economy
would be bigger if the UK were to stay in the EU.
But he added the size of that
"bonus" cannot be predicted with any certainty, and £50bn was not a hugely
significant amount in terms of overall government expenditure.
The manifesto pledges a
"written, federal constitution" that would make the National Assembly
for Wales and the Scottish Parliaments permanent institutions.
As it stands, the assembly can
technically be abolished through an act of parliament.
The Lib Dems would devolve powers
over criminal justice to politicians in Cardiff Bay, giving them control over
youth justice, probation services, prisons and policing.
Criminal justice in Wales is
currently overseen by the UK government in London.
Plans for policing promise to
invest £1bn across England and Wales to restore community policing,
"enough for two new police officers in every ward".
The Lib Dems promised to separate
England and Wales' legal systems to reflect the growing difference in laws, and
to devolve air passenger duty.
Police and crime commissioners
would be abolished and replaced with local boards made up of councillors, while
the party would fund a two percent pay rise for police officers.
The Lib Dems said it would
include the Welsh Government on UK policy making on drug policy and student
visas, and create a joint climate council of the nations to coordinate action
on the climate emergency.
On funding for Wales, the Lib
Dems said it recognised that Wales is underfunded and will seek "over a
parliament to increase the Welsh block grant to an equitable level."
Wales' devolved services are
mostly funded from the block grant, which comes from the UK government.
