How about having a PoD further back to get a few more Presidencies in. Let's go back to the revolutionary Sixties ...

A Very British Presidency: the first 50 years of the British Presidential Elections
Following the heavily publicised campaign by Anthony Wedgewood Benn, the second Viscount Stansgate, the Peerage Act of 1963 permitted owners of hereditary titles to disclaim their peerages. It became widely recognised that "nobility" could be a curse as well as a blessing. The nascent Republican movement seized upon this theme in their campaign through the early Sixties, building upon Tony Benn's successful campaign through the Fifties.
The revelation that the teenage Prince of Wales was being bullied at Gordonstoun proved a godsend for the Movement, as they constantly questioned whether this "hapless boy" should be forced into a lifetime of public service. The atmosphere of these times cannot be overlooked as a factor in the campaign, with the younger generation constantly questioning the way things had always been and seeking excuses to rebel against "The Establishment".
After the Great March of 1966, Prime Minister Wilson finally, and reluctantly, agreed to allow a free vote on a Private Members Bill that would put the matter to a public referendum. It is recorded that he was privately stunned at the large number of Labour MPs who voted for the bill, which passed by a majority of 17 votes in early 1967. In October 1967, the referendum was held.
The dislike of establishment figures for referendums was certainly a factor in the low turnout, as was the refusal of the Queen to make any comment on the issue. The shock victory for the "Yes" side was shown to be reliant on the boycotting of the event by a large component of the older generation. Nevertheless, the first British Presidential Election was set for Saturday the 1st of June, 1968 ...

It reportedly took a private plea by the former PM Alec Douglas-Home to convince Elizabeth Windsor to stand for the newly created Presidency, but once she decided to do so, the result was never in doubt. Ironically, by doing so, her actions doubtless legitimised the institution in the eyes of many who had denied the validity of the referendum result ...
... It wasn't until the third Presidential Election, in June 1976, that a genuine contest was experienced. President Windsor, runnig for her third successive term, came against the wily political operator Harold Wilson who had recently resigned as Prime Minister. In Wilson's memoirs, he revealed that his resignation had been triggered by a combination of his personal recognition that his once-formidable mental powers were starting to desert him and the distaste of his wife, Mary, for politics. He had therefore decided that a single term as the ceremonial President would be the perfect cap for his career and a recognition of his long-suffering wife as First Lady of the UK. It is ironic that although his intention was to be as apolitical as possible in the role if he had won, his candidacy was forever after seen as the one which politicised the Presidency. Nevertheless, President Windsor won re-election but by a far-diminished majority.
The Callaghan Government passed legislation in 1977 to impose a term-limit on the Presidency. An anonymous quote from the Labour backbenches was later ascribed to Dennis Skinner after it was widely circulated in the tabloid newspapers: "otherwise we'll simply be under the same woman for life anyway - it's just the bloody title that's changed". This act, limiting all future Presidencies to a maximum of two terms, has been cited as one of the reasons for the Labour loss in 1979 - being seen as an act of spite against the still widely popular former Queen passed near to the date when her Silver Jubilee would have been held if the monarchy was still in existence - but the economic situation would certainly have made a victory in such conditions extremely challenging in any case.
...
The first Presidential Election held on genuinely party lines was won by James Callaghan on the 6th of June 1980, in what has been termed the "Buyer's Remorse" Election. The event had far-reaching implications around the Commonwealth. As the same person had remained Head of State for the United Kingdom, they had dealt with the constitutional change by the well-precedented method of ignoring it until the situation became impossible to ignore. Elizabeth Windsor had remained Queen of Canada, Australia, New Zealand and many other Commonwealth Countries, despite losing her title in her homeland.
"We're not going to let any bloody Poms tell us who we can and can't have as Queen" was the theme in Australia, which was echoed in Canada (albeit in somewhat different words). It is ironic that this incident quite possibly saved the monarchy in these countries, as constitutional experts have often opined that in the absence of the Travelling Court, both countries would have voted themselves into Republican status themselves by the turn of the century. Prince Phillip was unofficially reported to be strongly in favour of the residency of the court in Ottawa during the summer months and Canberra during the winter and the wedding of Prince Charles to Lady Diana Spencer in 1981 solidified the monarchy during these turbulent times. The author will note, however, that the title of "Prince of New South Wales" was an ironic nickname bestowed at the time and does not have any constitutional legitimacy.

President Callaghan was defeated in the 1984 election by the Conservative candidate, Willie Whitelaw, signifying the first time that the Presidency and Prime Ministership were held by the same political party. The tight election was not declared until a full recount was held and supporters of the outgoing President were known to be privately blaming Roy Jenkin's candidacy for "splitting the anti-Tory vote".
...
The election of 1988 held no surprises, as President Whitelaw won re-election easily ...
... The 1992 Presidental Election, on the 6th of June 1992 saw the first contest between Presidential candidates who had formerly faced each other in a General Election. The battle between Margaret Thatcher and Neil Kinnock was very bad tempered and resulted in the election of the second female President of the United Kingdom. The ousting of Mrs Thatcher as Leader of the Conservative Party in 1990 doubtless contributed to her narrow victory, as a number of diehard Thatcherites seized the chance to vote again for their heroine in conditions where the negative aspects of her Premiership had apparently been overcome by her successor. However, her election proved to be hugely damaging for the Conservative Party, as her many disagreements with her successor became public knowledge and contributed to the perception of the Tories as a hopelessly split Party.
...
In 1996, Mrs Thatcher chose not to stand for re-election, citing disillusionment with the lack of true power of the Presidency. It had been expected that a "New Labour" candidate would sweep the field, but the candidacy of the maverick Labour backbencher Ken Livingstone as an "Independent Old Labour" candidate following his failure to secure the nomination as an official Labour candidate split the field. Anne Windsor, Princess Royal of the Commonwealth, won a colossaly split vote, riding an anti-politican tide and defeating Mr Livingstone, Jeffrey Archer, David Owen, David Steel, Frank Dobson (the official Labour candidate) and James Goldsmith. Her victory with barely 28% of the vote triggered the change of the system to the two-round runoff system we use today.
The second President Windsor never recovered from her loss of popularity following her perceived unsympathetic reaction to the death of Lady Diana in Paris in 1997, but has been creditted with the movement of the Presidency back away from partisan politics ...
...
The 2000 Presidential Election was a landslide win for Betty Boothroyd, the Labour candidate. Mrs Boothroyd was widely creditted with building on the work of President Anne Windsor in reinforcing the movement away from "petty party politics". She was invariably perceived as impartial, despite having originally been elected as a Labour MP and being the Labour Presidential candidate, and the Sun christened her "Queen Elizabeth the Third". Her re-election in 2004 was a mere formality ...

In 2008, despite the horrified campaign of the Guardian newspaper, Boris Johnson won election as President of the UK ...
