Liz Truss’ election as the UK’s next Prime Minister marks a significant turnaround after she almost missed out on the run-off altogether, having been behind both Rishi Sunak and Penny Mordaunt for most of the MP voting period.

A Hacked Off analysis of hundreds of articles published in Conservative Party-supporting newspapers reveals the extent of press bias during that period, which saw Truss drive past Penny Mordaunt at the very last round and into the final two – and in pole position to win the runoff and become Prime Minister.

Examining hundreds of articles in Tory newspapers across the two-week race to reach the final two, Hacked Off has found:

  • Penny Mordaunt’s campaign faced an extraordinary onslaught of hostile coverage across the press, with the Mail leading the way with a total of 36 articles found to be critical of the candidate for PM over the 2 weeks Tory MPs were voting – and only 1 found to be positive; despite an early lead among MPs she subsequently lost out to Truss
  • Mordaunt’s unexpectedly good showing in the first MP ballot appears to have been the catalyst for the press campaign against her – indicating a desire on the part of the Tory press to influence the race and push Truss across the finish line in front of her
  • The Conservative-backing press was split, with The Times tending to praise Sunak & criticise Truss, while the Mail attacked Sunak and relentlessly defended Truss
  • The Mail waged the most partisan campaign, with 89% of the paper’s references to Truss appearing to put her in a positive light, while only 10% of references to Sunak appeared to be positive
  • Kemi Badenoch won the best coverage overall, with each Tory paper tending to report positively on her campaign
  • The Conservative-backing press is showing signs of becoming more extreme in its partisanship, with – with the sole exception of Tom Tugendhat – more right-leaning candidates garnering more support than their more moderate competitors.

This research is based on a review of every article about the Conservative leadership race across the period July 7th to July 20th (the duration of the MP-balloting phase of the leadership race) which could be found on the websites of the UK’s four leading Conservative Party-supporting newspapers: The Times, The Telegraph, The Sun and The Daily Mail (and their Sunday papers).

Each article was analysed, and it was recorded whether the article would give, to an ordinary reader (who was not necessarily a supporter of the Conservative Party), a positive, negative, or neutral impression of each of the candidates. Candidates with fewer than 20 substantive references across these newspapers were not included in the analysis.

The findings paint a picture of a hyper-partisan, divided and agenda-driven part of the newspaper industry, determined to install their chosen candidate in Number 10.

There is nothing wrong with bias in the press, and coverage will inevitably favour one candidate over another.  But this research indicates a forceful effort on the part of some of these newspapers to have their chosen candidate elected.

The fact that Truss came from behind to ultimately win a place in the members’ vote after some newspapers campaigned so assertively in her favour suggests that – when it comes to the Conservative Party leadership (and by extension, the rest of the country in this case) – these newspapers are as powerful as they ever have been.

Hostility to Mordaunt was vociferous – and perhaps agenda-driven

The chart below shows exactly how the Tory press covered each candidate in this election, by giving a net figure for positive references to each candidate from each paper (the net being the number of positive references minus the number of negative).

It is a mixed picture for most candidates, but for Penny Mordaunt it shows net hostility from all titles, with The Telegraph and The Mail covering her campaign particularly negatively.

The chart below shows the net positive references (positive references minus negative references) to the most-covered candidates in Conservative-backing newspapers on each day of the race.  Day 1 is July 7th – the date of Johnson’s resignation – and day 14 is July 20th: the conclusion of the race, when Sunak & Truss were chosen for the membership run-off.

This suggests that it wasn’t until the first MP ballot was held (day 7) that coverage began to shift away from Mordaunt.  This was perhaps a reaction to Mordaunt’s surprisingly positive result in that first ballot, in which she placed second.  At that point in the race, Sunak and Mordaunt – two candidates perceived to be among the more moderate of those standing – were on course to go to the members’ vote.

From that point on references to Mordaunt become extremely negative, and she suffered deeply hostile coverage for almost the entire week going into the final MP ballot.


The Tory-supporting press was heavily divided, with The Mail backing Truss and The Times supporting Sunak

The chart below shows the difference in net positive coverage of the between The Mail and The Times.

The most significant difference in net coverage among the papers was between Truss & Sunak.  While The Times, which was more balanced than The Mail overall, gave better coverage to Sunak and poorer coverage to Truss, the Mail repeatedly attacked Sunak and defended Truss.

In general, The Mail’s coverage was viciously partisan, with the paper clearly targeting Mordaunt and Sunak, while praising Truss.

This perhaps marks a continuation of the Mail’s coverage of the Johnson administration, which was far more positive than rival newspapers (even on the right).

The balance of coverage from the Mail on the top three candidates – Mordaunt, Sunak and Truss – shows overwhelming bias and partisanship.

The balance of The Mail’s coverage: by candidate

The Conservative-supporting press has become more extreme

Overall, the further to the right candidates were positioned, the more likely they appeared to garner support from the Conservative-supporting press.  In fact, the most right-leaning candidate of all, Kemi Badenoch, secured the most favourable coverage.

The only exception to this rule was Tom Tugenhadt – who achieved positive coverage despite his status as the most moderate of the candidates standing.

The chart below gives the net positive coverage achieved by each candidate, and orders them from the most moderate to the most extreme (a judgment based on the limited policy announcements made by each candidate).

About this research

  1. This research was carried out by manually searching & reviewing the websites of the newspaper titles cited (which includes content from their Sunday editions) for substantive references to the candidates. Let us know if we have missed any.
  2. References were categorised as to whether they would be likely to give an ordinary reader a positive, negative or neutral impression of the candidate in question.
  3. Candidates with fewer than 20 substantive references were discounted from the analysis (but they are included in the raw data).
  4. The political leanings of the candidates, as set out in the final chart in this article, are a judgment based on the (limited) policy announcements made by each of the candidates in the course of the race.
  5. The four newspapers were chosen because each had a history of 10 years or more of support for the Conservative Party in General Elections (the Express were excluded, for example, because they backed UKIP in 2015).

Newspapers seeking to influence the outcome of elections is nothing new, but the ferocity of the Tory press’ campaign against Penny Mordaunt’s candidacy suggests that some titles are becoming more desperate in their attempts to move voters one way or another.  There is not even a pretence of balance in the overwhelmingly hostile coverage faced by Mordaunt, particularly from the Mail, which is perhaps embittered by its failed attempts to defend the outgoing Johnson administration.

The fact that Mordaunt ultimately lost out to the Mail’s favoured candidate Liz Truss, who has gone on to win election as Prime Minister, shows how powerful newspapers still are in politics.

The way Conservative-supporting newspapers, on balance, rallied around the more right-wing candidates suggests that the Tory-backing press has become more extreme and is shifting further away from the political centre-ground in those newspapers’ leanings and coverage.

The fact that even Rishi Sunak – a Chancellor of Johnson’s administration and committed Brexiteer – now appears to be considered too “left-wing” for The Mail and The Telegraph shows just how extreme the Conservative-backing press has become.

There is nothing wrong with partisanship in the press in principle, but newspapers becoming fanatically and factionally aligned with a ruling political party raises the risk of corrupt and unhealthy relationships between politicians and the press.

Leveson Part Two was intended to investigate allegations of corruption between politicians and editors (among other instances of corruption), but the Inquiry remains formally closed after politicians themselves (including Liz Truss) voted not to complete the Inquiry.

Conservative Party members – and the rest of the public – deserve better.
