Two clues have beaten me - and it's now Tuesday! I give up.
30a. It's said to stop people entering a?e?m?n? (Perhaps this ends with 'ing')
and
42d. Really like going by private transport - an unfashionable habit? ?e?d?g?n. I thought this might be cardigan but I have 'scheme' for 47a and I've never come across a cerdigan! Help please. Thanks in advance.
