BIRMINGHAM, England (Reuters) - Reform UK leader and Brexit campaigner Nigel Farage took aim at Britain's governing Labour Party on Friday, telling supporters his right-wing party was gaining voters disaffected with the government and would win the next election.

Nigel Farage has said "bigots" and "extremists" are not welcome in Reform UK, as he seeks to "professionalise" the party after its election success. Addressing its annual conference in Birmingham, the Reform UK leader said the party was "coming of age" after winning its first MPs in July.
