The EU referendum campaign officially begins on Friday, ending in a vote on 23 June to decide whether the UK stays in or leaves the 28-member bloc.
Britain Stronger in Europe and Vote Leave are expected to focus on core messages in speeches and rallies.
Former chancellor Alistair Darling will point to “credible warnings of economic disaster”, should the UK leave the EU.
But Leave campaigners will say the UK’s contributions to the EU should go towards the NHS instead.
During the 10-week referendum campaign period, which runs until polling day, campaigners are subject to spending limits of between £700,000 and £7m.
