Jeremy Hunt took a stroll beside the River Dart with his wife, Lucia. He has grown in popularity since the first round of voting in the party leadership contest

Tory voters now believe that Jeremy Hunt would make a better prime minister than Boris Johnson after two weeks of the Conservative leadership campaign.

In the past fortnight the number of Conservative supporters who think that Boris Johnson would make a good prime minister has dropped from 61 per cent to 55 per cent, according to the pollsters YouGov.

At the same time Mr Hunt’s ratings have risen significantly since he came through the first round of voting to take on the former foreign secretary in a vote among Tory members. Some 61 per cent now say that Mr Hunt would be a good prime minister, up from 45 per cent at the previous poll.

However, Tory voters still choose Mr Johnson over Mr Hunt
