The Royal College of Midwives (RCM) said 57% voted to accept the deal, with 43% rejecting it in a turnout of 48% of eligible members working in the NHS in England.

The offer covers two pay years - an additional one-off amount for 2022/23 and a 5% wage rise for 2023/24.

Alice Sorby, director of employment relations at the RCM, said: "The offer was not perfect, and it was not everything we asked for or that midwives and maternity support workers deserve.

"However, it was a step forward from the Government's entrenched position on 2022/23 pay and improved on its directions to the Pay Review Body for 2023/24," she said.

"It was the power of the collective unions standing together, with our members behind us, that brought the Government to the table and led to this improved offer."

The pay offer was made to NHS staff on Agenda for Change contracts which includes the majority of workers apart from doctors, dentists and senior managers.

The largest NHS union, Unison, voted overwhelmingly to accept the offer aimed at resolving the long-running NHS dispute.

But not all unions have followed suit. The Royal College of Nursing rejected the offer and set out plans for more strikes, while workers in the Society of Radiographers in England also voted against the pay deal.

Other unions - including Unite, GMB and the Chartered Society of Physiotherapists - are set to announce their ballot results in the coming days.

The NHS Staff Council - made up of health unions, employers and Government representatives - is set to meet on 2 May to discuss the outcomes of the consultations by each union and report back to Government.

Midwives' acceptance of the NHS pay offer comes as more than 400 HMRC workers announced they will strike for 18 days in May and June.

A total of 432 customer service advisers in Glasgow and Newcastle upon Tyne will walk out on 10 -12, 15-19, 22-26, 29-31 May and 1-2 June.

The strike by workers in the Personal Taxation Operations on Employer Service department in HMRC is likely to cause significant problems for businesses across the UK.

The action is expected to impact the Employer Helpline, Construction Industry Scheme (CIS) Helpline, HMRC's Student Loans Unit, PAYE registrations, maternity, paternity and sick pay, disputed charges, penalties, expenses and benefits, and one of the government's flagship small business policies, Employment Allowance.

The Public and Commercial Services Union (PCS) said the strike is over pay, pensions, job security and redundancy terms.

PCS general secretary Mark Serwotka said: "Our hard-working members in HMRC are fed up with being treated with disdain by a government that doesn't seem to care about its own staff.

"If they did, ministers would be able to stop this strike action tomorrow by making a fair offer to help our members through the cost-of-living crisis and beyond."

More than 133,000 civil and public servants are also due to walk out on Friday.
