Your report on the conviction of John Sweeney should be essential reading for some of my colleagues in the European parliament who have consistently argued against the very programme that brought this murderer to justice (Report, 4 April). Last year the Guardian reported that the UK requested Eurojust's help in more cases than any other EU country. Yet time and again, the Conservatives and Ukip in Brussels have refused to support the organisation, a body set up to help the police work more effectively with their colleagues in other EU countries. Perhaps they don't see the link between abstract agreements in Brussels and the reality of fighting crime.

• That general election editorial aside, the Guardian's Newspaper of the Year Award is well deserved. However, while WikiLeaks symbolises what the paper stands for, the open and discursive nature of the letters page is its core value.

• Having just listened to the Guardian staff's cover of Creep for the 100th time, I am writing to plead for it to be put on iTunes. Surely Thom Yorke and co would agree if the proceeds went to charity?

• In your article regarding Adele's domination of the charts (Queen of charts, 5 April), you say that the record for continuous tenure of the No 1 position is held by Bob Marley in 1984 with 12 weeks. Simon and Garfunkel held the position for 13 weeks with Bridge Over Troubled Water. They then returned for further, interrupted, spells at No 1, making a total of 33 weeks. Adele has a way to go yet.

• Do Wittgenstein's words about dogs apply to horses (Letters, 1 April)? Given that he also said, "If a lion could talk, then we could not understand him", perhaps we are saddled with a human-equine inter-flank so unstable that we can't trot out bits of mane principles on the hoof, and should bridle our words until error withers and truth reins?
