In his meeting with Vladimir Putin at G20 last night, Prime Minister David Cameron reveals he has “raised concerns” with the Russian President about the country’s controversial anti-gay “propaganda” laws ahead of the Sochi 2014 Winter Olympics.

The Foreign Office confirmed earlier this week that Mr Cameron would indeed raise the issue of the legislation, which, passed by Vladimir Putin in June, bans the promotion of “non-traditional relationships” in Russia.

Following a “candid” 2am meeting in St Petersburg last night, Cameron this morning has tweeted that he “raised concerns about gay rights.”

ITV reports that the talks lasted for 35 minutes and consisted of a “business-like” atmosphere.

Number 10 described Mr Putin’s responses as “evasive” and the meeting reflecting their “strong differences”.

Last month, David Cameron told the writer and broadcaster Stephen Fry that he shared his “deep concern about the abuse of gay people in Russia.” Mr Cameron added that this abuse can be challenged by attending, not boycotting the Winter Olympics.

The Prime Minister’s comments comments echoed those of the US President Barack Obama. Mr Obama told a press conference: “If Russia doesn’t have gay or lesbian athletes, it’ll probably make their team weaker.” Adding: “I do not think it’s appropriate to boycott the Olympics.”

Obama is also reportedly to meet LGBT activists in the Russian city of St Petersburg during his trip to the city as part of a G20 Heads of Government meeting.
