A controversial polyclinic will benefit from a £5.2m cash boost in the wake of fears over the closure of A+E and maternity wards.

The Government announced Kingston NHS would receive the money which will help pay for the planned centre at the old Surbiton hospital site, due to open early next year.

The cash will help fund services including diagnostics, community health services and therapies, according to Kingston and Surbiton MP Edward Davey.

Kingston Hospital will also get a £800k as part of the funding to upgrade a number of diagnostic services including x-ray and ultrasound equipment.

However the announcement comes in the wake of fears Kingston A+E and maternity wards would be forced to shut following a review into NHS south west London.

Either Kingston, Epsom and St Helier, Croydon or St George’s would lose both maternity and A+E if the Better Healthcare Closer to Home final recommendations are approved later this year.

But the new energy secretary moved to reassure Kingston patients over the closures, despite both wards being under budget review.

Mr Davey, who campaigned against hospital closures in 2010, rubbished claims he is putting his new job in the government ahead of constituency and said he is watching the situation "like a hawk".

He said: "From my conversations to the evidence of Kingston’s strong performance, from the difference this time compared to last, people can be reassured.

"Naturally I am monitoring the situation like a hawk and if I get a whiff of danger I will be the first to campaign, and my position in the cabinet won’t prevent me making my case."

Mr Davey said the money was a welcome “shot in the arm”.

He said:"This was unexpected three months ago, so it helps massively on the delivery of the new health facilities and has knock-on benefits for the budget of NHS Kingston.

"It is a real boost for the improvements underway to local primary health care services.”

The allocation is part of a £330m announcement made by David Cameron, which will fund new operating theatres, A&E departments, CT scanners, and cancer therapy and ultrasound equipment across the country.

Mr Davey and fellow Kingston MP Zac Goldsmith are seeking a meeting with the authors of the review.

The options will now be scored by a panel of 60 people in May including members of the public, before going to a formal public consultation.
