Battle heats up to be next British PM

After debate, four rivals to front-runner Boris Johnson remain in the race

The five remaining candidates in the Conservative leadership race to be the United Kingdom's next prime minister set out their differing approaches to Brexit in a live televised debate on Tuesday evening, ahead of a third ballot due to be held on Wednesday.

During the hourlong exchange, the five were challenged on issues such as taxes, Islamophobia and the environment. The five started by trading blows over whether the UK should leave the European Union on Oct 31, regardless of whether details with the EU have been ironed out by them.
