Public support for Donald Trump's removal from office is the highest it has ever been, according to a new poll.

Fifty-five per cent of those asked said they were in favour of the US president's conviction by the Senate, a figure which has shot up from 48 per cent the week before.

Meanwhile, the number of people against Mr Trump's removal has dropped to an all-time low, according to the MSN poll.

On Christmas Day, 40 per cent were opposed to the Senate voting to convict the president, who has been impeached over his dealings with Ukraine and an alleged subsequent attempt to obstruct congress.
