There were nearly 5.4m visits to A&E during January to March – down slightly on the same period the year before.
Long waits were also seen in other parts of the hospital system.
A fifth of those who arrived at A&E – 1m – were admitted to hospital for further treatment.
Over 113,000 of those admissions waited over four hours for a bed – known as a trolley wait. That is double the number from the January to March quarter in 2014.
Labour immediately linked the figures to cuts in GP services – the topic of their latest election poster.
The poster reworks the Conservatives’ “Labour isn’t working” image of 1979 by depicting a huge queue outside a waiting room with the title: “The doctor can’t see you now.”
Shadow Health Secretary Andy Burnham said: “After five years of David Cameron, A&E waits are at their worst level for a decade and patients are finding it harder and harder to see a GP.”
A Conservative spokesperson said: “A&E units across the UK faced unprecedented demand this winter, but English A&Es see 3,000 more patients a day within four hours than in 2009, and perform better than Scotland, Northern Ireland and Labour-run Wales, so it is completely wrong for Labour to try to turn this into a political football.”
