The UK is assuming its year-long presidency of the G8 group of nations. The presidency – which rotates through the G8 members – means it will host the annual leaders' summit and choose the global priorities that are discussed. June's summit is to be held at Lough Erne, in County Fermanagh, while topics discussed will include tax havens. The G8 is made up countries who have, historically, been the richest in the world – France, the US, Russia, Japan, Germany, Italy, Canada and the UK. As prime minister of the presidency holding nation, David Cameron has said he wants to focus on combating trade protectionism, cracking down on tax havens and promoting greater government transparency.
