Should we stay permanently on British Summer Time?
Dr Mayer Hillman, a public policy specialist at the Policy Studies Institute wants the UK to keep British Summer Time throughout the year. Do you support the idea?
Dr Hillman says the extra hour of evening daylight would give everyone more opportunities to be active outdoors and help us become fitter and healthier.
The ending of GMT is supported by the Mayor who says London's economy could be boosted by more than half a billion pounds if the clocks were not turned back.
However, permanent summertime is unlikely to be well received in northern England and Scotland where an extra hour in the mornings would see the sun rising after 9am and children facing the prospect of going to school in the dark.
Do you think the country would work with two time zones?Are you in northern England and Scotland? Are you affected when the clocks change? Send us your comments and experiences.
