In reply to The Ice Doctor:

The problem is that it's so badly written that on first reading it seems that the second infinitive (to undermine) refers to safeguards in the same way that the first one (to ensure) does. Then when you read it again you realise that 'to undermine ... account' is one big phrase relating to 'its powers'. Not only is this double infinitive confusing, but the sentence is not helped by the strange double-negative effect of 'abuse' and 'undermine' in the weird phrase 'abuse the powers to undermine'. It means something like 'to ensure that the Government doesn't overreach itself with its powers to undermine Parliament's role in holding the Govt to account'. It's still a hell of a mouthful, but I can't be arsed to have a go at re-writing it.
