Slast,
I believe you have missed my meaning. The pension you received was that which you were contracted to receive and thus paid the contributions necessary, as in that which the details were given within the contract, not that the pension received was a 'given', to use teenager parlance!
Perhaps I should have worded it better!
I also have contributed to the charity you mention above! I only wish my pension pot were the size that some Daily Mail readers tell us all they should be!!!
