As they embark on the last push of their general election campaigns, the U.K.'s party leaders have been doing their utmost to charm voters with their attempts to appear as average as possible—a tactic often questioned or mocked by the media and the public.

But despite the skepticism, British politicians aren't the only ones trying to eat bacon sandwiches gracefully or posing for "selfies."

CNBC takes a look at the politicians around the world trying to act "normal."

Like his opponents in the upcoming election, U.K. Prime Minister David Cameron has participated in the odd selfie and soccer kick-around. He's also broadcast his taste in television, claiming to be a fan of HBO series "Game of Thrones" and visiting the film set in Belfast, Northern Ireland this April.

His visit turned political however when Cameron told the BBC public broadcasting service that he'd visited Northern Ireland because the Conservatives were the only party "to stand in all four nations of the United Kingdom."

Cameron has also shared his food preferences with the public. Filmed by tabloid newspaper The Sun, the Prime Minister gave viewers a taste of his daily life by preparing a "Sardines a la Cameron" sandwich with sardines, tomato and lemon on camera.

The former U.S. President worked the "average Joe" card hard and his efforts helped spawn one of the most commented-upon political "bromances" of recent years — that of George Bush and former U.K. Prime Minister Tony Blair.

Bush encapsulated the relationship when he allegedly greeted his U.K. counterpart with "Yo Blair" at a G-8 conference in Russia in 2006.

The pair's relationship sparked a series of mocking online videos, set to soundtracks such as Lionel Richie and Diana Ross's "My Endless Love."

While she may be the most powerful woman in the world, according to Forbes magazine, German Chancellor Angela Merkel, is not above cracking a joke or showing her human side.

She has touted her love for beer and maintained her composure when a waiter accidentally spilt some alcohol on her at a party in Germany in 2012.

Plus, when visiting the U.S. in 2011, Merkel presented Hillary Clinton with a framed front page clipping of German newspaper, Frankfurter Allgemeine which displayed an image showing both women's love of pantsuits and their similar fashion sense.

Labour Party leader, Ed Miliband, the main opponent to the current U.K. Prime Minister, has wiped the floor clean in his attempts to act like a "typical Brit."

First up: Trying to eat a bacon sandwich. Last year, Miliband was mocked by both fellow politicians and the public after he was filmed attempting to eat a quintessentially British tomato-ketchup-filled "bacon butty".

Even when trying to perform good deeds, Miliband has received some not-so-positive publicity, including when he was photographed donating money to a female beggar in Manchester, U.K. And when he visited seriously flooded areas of the England in February 2014, people took more interest in his fashion sense—specifically, his wellington boots—than in his political efforts.

Tony Abbott is known to be a keen sportsman, but his choice of sportswear is often more commented upon than his athleticism.

Even prior to his role as Prime Minister, Abbott was mocked by both Australian and international media for wearing tight-fitting, skimpy "Speedos" when swimming, especially during charity swims and competitions. Perhaps in consequence, Abbott announced the 2013 election campaign would be a "budgie smuggler (Speedos) free zone," according to Australia's Business Review Weekly.

Like the U.K.'s Cameron, U.S. President Barack Obama likes to show off his taste in movies and entertainment. Obama has been caught on camera using a selfie stick, playing basketball and discussing his thoughts about pop musician, Kanye West.

While in office, Obama has attempted to charm the public with a variety of ploys, from brandishing a Star Wars lightsaber on the White House Lawn in 2009 to drinking a pint of Guinness in a pub with First Lady, Michelle Obama in 2011.

After announcing his presidential bid for the 2016 U.S. elections in March, Republican Ted Cruz may have to do more than "filibustering" to win votes.

In September 2013, Ted Cruz hit headlines when he spent 21 hours speaking against President Obama's Affordable Care Act. In between long monologues on his fierce opposition to the health care law, he also discussed Star Wars, read Dr. Seuss' "Green Eggs and Ham" and praised Ashton Kutcher and White Castle burgers.

Almost unheard of at the start of the century, the leader of the populist UK Independence Party, Nigel Farage, has risen to fame on the back of his frank opinions and love of cigarettes and drinking a pint of bitter in a British pub.

Last winter at a conference in Torquay, Farage's own party presented him with a fruitcake, after Prime Minister Cameron allegedly described UKIP members as "fruitcakes, loonies and closet racists." Farage pronounced the fruitcake "delicious" before stating: "the more they throw all these words at us, the more people vote for us."

Former Prime Minister of Italy, Silvio Berlusconi, is famed for his wealth and love-hate relationship with the courts, but also for his love of publicity, sports and women.

Berlusconi is honorary president of renowned football club, A.C. Milan, which he acquired in 1986; he has often been photographed at its matches in the past.

As well as being frequently photographed with beautiful women—or if not, cute animals—Berlusconi is known for his soundbites on politics and other topics. Famed comments include "women are lining up to marry me. Legend has it, I know how to do it".

In the run-up to this year's election, Deputy Prime Minister and Leader of the Liberal Democrat party in the U.K., Nick Clegg, has tried showing the public his softer side.

He has been photographed with small hedgehogs, caught up with reality TV star, Joey Essex, played a round of ten pin bowling and got his hands dirty gardening and talking to mechanics.

But will this get the public's vote? Clegg won hearts during the 2010 General Election, but recent polls show the public are less convinced than they were five years ago.
