Britain's EU "In" campaign lead narrows - Ipsos MORI poll

The campaign to keep Britain in the European Union saw its lead over the rival 'out' campaign fall sharply in the last month, according to a telephone opinion poll by Ipsos MORI. The poll of 1,023 adults was conducted between March 19 and March 22, meaning it does not fully reflect any impact on voting intentions of bombings in Brussels on March 22 which killed 35 people.
