SIR - To add to Tony Blair's legacy of bringing more terrorism to this country and against all the guidance and unsponsored scientific evidence, we now have the Government permitting introduction of GM potato crop trials into the fields in the UK.

Government ministers are claiming that there will be strict control against contamination, so they obviously have gathered together all the wildlife such as birds, insects, field mice, rabbits etc to tell them that if they get into GM fields they must not go into any other fields but stay put forever.

And on national radio, we even had a minister making reference that it was to avoid another potato famine like in 1845.

In America, with giant politically influential GM seed companies such as Monsanto, they are now reaping the results, with all this year's long grain rice crops now contaminated from GM trials that were carried out five years ago.

We the British people must stop GM.
