Elizabeth Warren could be unintentionally benefit from the impeachment inquiry as claims over her Democratic presidential rival Joe Biden’s activities in Ukraine dominate the headlines, polling experts have predicted.

The US senator for Massachusetts has enjoyed a remarkable surge in the polls of who Democrats want as their White House candidate at the 2020 election and is now neck-and-neck with Mr Biden, long seen as the front-runner.

Despite the impeachment probe targeting Donald Trump and his alleged abuses in office, some are predicting the drive could inadvertently rebound and politically damage Mr Biden, the former US vice president.

At the heart of the impeachment inquiry are claims that Mr Trump pressured the Ukrainian president to look into Mr Biden and his son Hunter Biden’s activities in the country.

Mr Biden, while in office, called for Ukraine’s prosecutor to step down. At the time his son Hunter worked for a Ukrainian gas company. The prosecutor was once investigating the head of that company.
