Theresa May urges members of her cabinet not to take anything for granted by depending of opinion polls

Having learnt from previous experiences, British Prime Minster has warned members of her cabinet never to depend on public survey and fold their arms for the opposition take over power, as election is not won by mere public opinions.

The admonition was made by the PM during a cabinet meeting, as she said polls have been proved wrong on several occasions, citing the the EU referendum, the 2015 election and the US presidential election.

Echoing comments made by Jeremy Corbyn himself, Mrs May pointed out the current Labour leader was considered a rank outsider to succeed Ed Miliband before pulling off a shock victory.

Also in a similar vein, party chairman Sir Patrick McLoughlin said the Conservatives would need to "campaign hard for every vote, in every part of the country".

Senior Conservative members have constantly talked up the predictions of Labour doing well, a strategy perceived by many Westminster observers as a bid to avoid complacency among its supporters.

Making his contribution, a strategist of the Conservatives has also expressed concern that if their followers believe victory is a foregone conclusion then they may not turn out to vote.

Speaking further Mrs May told ministers how important it is to for them to pass the message that the country was being offered a choice between what she called "strong and stable leadership" under her or "a coalition of chaos and instability led by a floundering, weak and nonsensical Jeremy Corbyn that will put our nation's future at risk".

But in an indication of how high the Tories are setting their sights in this election, Mrs May parked her tanks directly on Labour's lawn by making a visit to South Wales.

It comes after a poll suggested the Conservatives could take a majority of votes cast in Wales for the first time in more than 150 years.

Mrs May warned again against complacency during the trip, telling a crowd in Bridgend that "every single vote will count".

The PM told them the poll was "the most important election this country has faced in my lifetime".

"An election in which every single vote will count. A really important election for the future of this country," she said.

"A vote for any other party would be a vote for a weak and failing Jeremy Corbyn propped up by a coalition of chaos which would risk our national future."
