Nearly half (47%) of those surveyed for a YouGov poll found that Mrs May is most similar to the first female Prime Minister, while 31% said they were different.
The comparison is no bad thing – recent research found that 43% of Brits describing Mrs Thatcher as a good or great PM.
It may be quick to dismiss the similarities – both are female leaders of the Conservative parry and the only two women who have led the country – but the public believe the two also share similar qualities.
The YouGov research found that a majority of Brits (56%) found Mrs May decisive and has what it takes to get things done, while 44% also found her to be good in a crisis.
The results are a stark difference from Labour leader Jeremy Corbyn, who still remains deeply unpopular with the public.
Numerous polls have shows Mrs May beating Mr Corbyn on who would make the best Prime Minister by huge margins – as well as a consistent poll lead for the Tories.
However, YouGov polling suggests a change in Labour leader could even things up a little.
Mrs May’s strengths (47%) are seen as what make her the best PM – but nearly the same figure (46%) believe Mr Corbyn’s weaknesses are to blame.
With Mr Corbyn unpopular with the party’s own supporters, a change of leader could see grudging support for Mrs May drift back to a more popular person at the head of Labour.
With Brexit set to dominate the next few years of the political cycle, Mrs May’s future decisions and a volatile political landscape could see her fortunes change quickly.
