The battle over who should be the next European Commission President is already well under way – with the UK's Conservative Prime Minister David Cameron leading a fight to stop Luxembourg's Jean-Claude Juncker from taking the top job at the European Union.
But the fight for who should lead another branch of the Brussels power structure -- the European Parliament -- is about to begin. And Cameron is leading the charge there as well.
Facing an anti-European backlash at the polls, the U.K. prime minister is battling to reform the power structure of 28-country EU, which he sees as spendthrift, undemocratic and meddlesome. If he doesn't get his way, he has pledged a referendum on his country's membership by 2017.

And it looks as though the battle over who leads the EU will come to a head at next week's summit in Ypres, Belgium.
Taking up the challenge to become President of the European Parliament, which has a massive say on EU policy and spending, is Sajjad Karim, a British Conservative with 10 years' experience as a European lawmaker.
Karim's hat is the first to be thrown in the ring and he does it with the backing of what could soon be the third largest political group in the EU Parliament. The European Conservatives and Reformists Group (ECR), is a coalition of right-wing parties was formed by Cameron in 2009. Its ranks have recently been swelled in the latest round of parliamentary elections.
"It's a shrewd move," Pawel Swidicki, research analyst at Open Europe, told CNBC. "Karim stood for the same position a couple of years ago, and managed to get a lot of support beyond the ECR Group."
Sajjad Karim will hope to gain more votes from his fellow EU peers within the parliament to gain the necessary majority to win the seat. The EU Parliament's president all legal and international matters associated with the institution. The EU budget, for example, needs the president's signature before it can be adopted.
However, Karim faces a fierce fight. For while his overall opposition may have yet to find their leading men, the parliament's two leading political groups – the center-right European People's Party (EPP) and the center-left Progressive Alliance of Socialists and Democrats (S&D) – have together managed to wall out previous challengers, by strategically voting for each other to effectively control the presidential seat.
