THE Tories have lost their lead over Labour as Boris Johnson’s “good Prime Minister” rating has plummeted to its lowest since he entered No10, a new poll reveals as a sleaze storm rages at Westminster.

The UK wide Ipsos MORI survey put the Conservatives on 35%, down four points on September, Labour unchanged on 36%, the Greens up a startling five points to 11%.

For the first since Johnson gained the keys to Downing Street, a majority of adults in Britain disagree that he has what it takes to be a good Prime Minister.

However, despite the grim findings for the Prime Minister, Sir Keir Starmer and Labour do not appear yet to have made any dramatic breakthrough in winning over voters, according to the poll commissioned by the Evening Standard.

The poll was largely conducted before the Owen Paterson sleaze scandal exploded at Westminster.

An emergency anti-sleaze Commons debate is being held on Monday after the Government sought to tear up the disciplinary system and block a 30-day suspension for the ex-Cabinet minister for breaching lobbying rules.

It came amid a string of other controversies including over Johnson’s free holiday at a villa near Marbella owned by the family of Lord Goldsmith, funding for the refurbishment of the PM’s Downing Street flat, and claims most Tory treasurers over the past two decades who have donated at least three million to the party have been offered peerages.

The survey also shows growing disquiet over the Government’s handling of the Covid-19 pandemic and may have been swayed by the COP26 summit raising awareness of climate change issues, with the Greens posting what is believed to be their best result on record.

Its key findings include:

* Fifty-five per cent of adults disagree that Johnson has what it take to be a good Prime Minister, with 34% saying he does, giving him a net score of -21. This is a sharp drop from +2 in June, and the lowest score since June 2019, a month before he walked into No10.

* Forty-one per cent do not believe Sir Keir has what it takes to be a good Prime Minister, with 25% thinking he does, a net score of -16, up from -24 in June.

* Sixty-one per cent of people say they are dissatisfied with Johnson, and 34% satisfied, giving a net score of -27, a big drop from -12 in September. It also equals his lowest satisfaction rating as PM, which was last October.

* The Government as a whole fares even worse, with 62%  dissatisfied, and 29% satisfied, a net score of -33, compared to -16 in September, the worst since last October.

* Half of voters are dissatisfied with Sir Keir, with 29% satisfied, a net rating of -21, slightly better than the -25 in September.

* In a sign of divisions within Labour, 42% of its supporters are dissatisfied with Sir Keir, and the same proportion satisfied, a net rating of zero, little better than the minus three in September. In contrast, 72%  of Tory supporters are satisfied with Johnson, and 22% dissatisfied, a net score of +50, down from +56 in September.

* Nearly half of adults (48%) say the UK Government is handling the Covid-19 pandemic badly, up 12 points on September, and 36% say it is doing well, down eight points, the worst score since the end of last year.

Despite the UK having significantly higher coronavirus deaths and case numbers than many other European countries, ministers are sticking to their Plan A rather than reimposing limited restrictions such as mandatory face masks on public transport.

Gideon Skinner, head of political research at Ipsos MORI, said: “The Conservatives are facing challenges on a number of fronts.

“The pandemic is far from over with high levels of infections, while we are also seeing worries about the economy, the NHS, the knock-on effects of Brexit, and other issues, all leading to rising concerns about the direction of the country - even before any long-term impact of the standards row last week.

“Climate change is also in the news and in the public’s priorities, which may help to explain the notably good figure for the Greens.

“So the Conservatives are no longer in as strong position as they were over the summer – although the public are still not convinced by Labour as an alternative.”

Many Tory MPs were furious at being ordered to vote last week to ditch the current Commons disciplinary system to block the suspension of Paterson for breaching lobbying rules and to bring in an appeals mechanism, only for No10 to do an extraordinary u-turn 24 hours later after being hit with a backlash.

Former Prime Minister Sir John Major has suggested the Johnson administration has engaged in “politically corrupt” activities.

Johnson promoted Liz Truss to Foreign Secretary in September in what was seen at Westminster as a move to undermine Chancellor Rishi Sunak’s rise to being a new Tory leader-in-waiting.
