The cyclone in Burma has killed tens of thousands of people and left up to one million homeless.

Aid agencies are appealing for help and say the need is "immediate and vast". 

While there are questions over what access the Burmese government is giving to aid agencies, most say they have partners on the ground and they are confident aid will get through.

I am running 10k to raise funds for the the UK-based Disasters Emergency Commitee - an umbrella organisation of 13 major aid agencies.

Donating through this site is totally secure and, if you are a UK taxpayer, an extra 28% in tax will be added to your gift at no cost to you.

Many thanks for your support.
