UK adaptators

[Stephane Rondal]

Going to London in a couple of weeks (won't have time to attend
the London.pm meeting unfortunately), does any of you know
if I need a power adaptator and a telephone jack adaptator to connect
my laptop there.

My laptop is UK voltage and amperage friendly, but what worries
me are the plugs. Are UK power plugs the same as in Belgium?
And phone jacks.

Thanks for your help.
