LONDON (Reuters) - Britain's opposition Labour leader Jeremy Corbyn has overtaken Theresa May for the first time as voters' choice for who would make the best prime minister, a YouGov poll for The Times newspaper showed.

After PM May's botched gamble on a June 8 snap election deprived her Conservative Party of a majority, she is trying to strike a deal with Northern Ireland's Democratic Unionist Party to prop up her minority government.

When asked who make the best prime minister, the YouGov poll for The Times showed 35 per cent of voters would prefer Corbyn, while 34 per cent favoured May. The poll showed 30 per cent were unsure.
