Lives are at risk after Brexit unless there is continued research operation with the EU, Labour has warned.

Shadow health secretary Jonathan Ashworth will say it is “utterly unacceptable” for there to be uncertainty about the arrangements after Brexit.

He will also promise that Labour would ensure medics and carers from other EU states will continue to be able to come and work in the UK after it has left the bloc.

Mr Ashworth will visit Brussels in the latest sign of Labour’s push to build links with EU figures.

He will say Labour would seek to remain part of the European Medicines Agency (EMA), prioritise the negotiation of continued access to reciprocal healthcare schemes or a comparable alternative and stay part of the Horizon 2020 agreement on research funding.

He will vow Labour will not “sign off on a Brexit deal that turns the clock back on medical innovation” or means patients face longer waits for new treatments.
