I have fairly large sum of premium bonds, apart from being a poor investment in terms of return unless I win a decent amount, how safe are they if the markets continue to unravel ?

I have a large amount of premium bonds and I have good results for the last two years. Much better than if I had put it in a high interest account all depends if you are high rate tax payer or not as the winnings are tax free. As a high rate tax payer I have YTD made 12% on my investment so its great for me

Al NS & I investments are backed directly by government and as such are (they claim) 100% secure.

I am wrong to be concerned that the government is in more debt than the whole of the country put together? Is it matress stuffing time yet?

you must have my winnings! My returns have been absolutely shocking over the past 6 months, about £100 on maximum holding. Will be pulling out soon..

Send the money to me and I will give you better returns than that
