The Queen is set to deliver her speech setting out the new Conservative minority Government's planned programme at 11.30 today.

The PFS said the reality of facing a minority Government for an indefinite period means it would be difficult for tough, but necessary, decisions to be made about controversial issues like funding state pensions and long-term care.

Normally, these issues would be dealt with through a decisive election result, followed by a series of budgets and spending reviews, but with the Government’s hands tied by Brexit negotiations and no overall majority, it is likely that difficult decisions would be kicked into the long grass, officials warned.

The PFS insisted that “politicians must accept that they can't set out a clear vision of the future of welfare and individual responsibility on their own, and that they need an authoritative, expert voice to help them conduct a conversation with the public about complex welfare reforms”.

Keith Richards, chief executive at the PFS, said: “We can’t ignore the demographic and economic pressures facing our economy, and the new Government has to take responsibility for easing these pressures by making difficult decisions and introducing brave but prudent measures so that the public have a choice of mitigating any personal impact on them and their families.

“Understandably, Brexit will consume Government resources in the next couple of years but we must not let it detract from the economic and social challenges we face at home.

“An independent pensions commission was able to achieve a cross party consensus about auto-enrolment that has stood the test of time. We need the ongoing involvement of independent experts to avoid an inter-generational savings crisis.”

Following publication of John Cridland’s Independent Review of the State Pension Age in March, the PFS wrote to Chancellor Philip Hammond, urging the Government to rethink its short-term pensions strategy and to move forward with the report’s pragmatic recommendations.

In the letter, the PFS also put forward the idea of an independent pensions commission, tasked with establishing sustainable measures aimed at addressing the issues facing the public in retirement.
