The IPPR is suggesting that anyone who works in London should be entitled to an increased minimum wage, £1 higher than the rest of the country. One assumes this is due to higher living costs. Strangely the IPPR does not advocate a reduced minimum wage in areas like Wales or the North East where living costs may be below the national average. Funny that.
UPDATE: The ususal ignorant idiots have infested the comments, deliberately twisting what I wrote. I am not advocating a lower minimum wage for the North East and Wales, I am merely pointing out the perverted logic of the IPPR. Sigh.
