British lawmaker Cox was killed because of her political views: husband

Lawmaker Jo Cox, who was shot and stabbed a week before Britain's referendum on European Union membership, died because of her political views and had been deeply troubled by the tone of the campaign, her husband said on Tuesday.

Prime Minister David Cameron appealed to voters across the generation gap to back staying in the EU, two days before a closely fought referendum that will shape the future of Europe. The campaign to leave the EU has echoes of populist movements across Europe and in the United States.
