wrong BB ; northern rock most certainly is covered by by a UK government guarantee of 100% of deposits , and not the limited £35 K FSA guarantee
this guarantee has a cap as to total funds [ as held when the company was nationalised ] ; currently NR holds less than the limit and can take in funds with the guarantee
with regard to it being UK mainland only , this is wrong ; the guernsey financial services authorities have received confirmation from the british government that this includes funds held in the guernsey subsidiary , as with any funds held within the NR group ; I am afraid you are confusing this with the FSA guarantee
unless of course you are afraid the tories are going to get in and default on deposits in a company which is currently nationalised as NR guernsey is , of course
maybe you should check your facts before you post ? don't take my word for it , check with the british government and the guernsey financial services authorities
