Talk about an awkward Ed Miliband moment. The Telegraph reports this morning that t-shirts bearing the slogan “Thatcher: a generation of trade unionists will dance on her grave” are being sold at the TUC congress in Brighton. Guido has also found sick so-called Thatcher “party packs” on sale for those inclined to celebrate the death of an old lady.

According to the seller they have been pretty popular:

While Labour types on twitter have issued heavily caveated criticisms, so far there has been no comment from Ed on the taunting of Lady T.

Being stuffed full of union cash does put him in quite a tricky position – hardly wants to upset his paymasters who are obviously keen on dancing on Maggie Thatcher’s grave.

But maybe there’s another reason he hasn’t condemned them…
