Lead UK EU referendum campaigns named: BBC

Vote Leave and Britain Stronger in Europe have been designated as the official Leave and Remain campaigns in June's EU referendum, the BBC reported, citing the Electoral Commission.

Vote Leave - backed by Boris Johnson and Michael Gove - saw off a challenge from a rival campaign Grassroots Out, backed by UKIP leader Nigel Farage.

The campaigns will be allowed to spend up to £7m, get a free mailshot, TV broadcasts and £0.6m in public funds.
