This week, hundreds of thousands of people will join the annual act of remembrance to commemorate those who have died in war, proudly wearing a poppy to honour the fallen.

However the simple flower emblem, which has been used since shortly after the end of World War One as it was the only thing to grow on the devastated battlefields of Belgium and northern France, has once again become an issue in itself.

Is the decision to not wear one an act of disrespect?

The Daily Mail newspaper is running a campaign, demanding that Premier League football teams have a poppy embroidered onto the shirts they wear this weekend. Twelve clubs initially said they would do so, but as the Mail turned its ire on those that didn't, all bar two -- Manchester United and Liverpool -- have now agreed to make the gesture.

The Mail said football teams wearing the poppy sent out a "powerful message of solidarity" to Britain's armed forces.

"All too often footballers - on and off the pitch - set a dreadful example to their young supporters," the paper said in its editorial. "It would be to their eternal shame if Manchester United and Liverpool snub the opportunity to demonstrate that their sport can be a force for good."

Footballers are by no means the first to be criticised for failing to wear a poppy. BBC, ITV and Sky News presenters and reporters all wear a poppy when they appear on our screens following complaints in the past, and even producers on "Strictly Come Dancing" have come in for criticism this year for suggesting contestants should not wear the emblem because of health and safety fears. They have since backed down.

A few years ago, Channel 4 news presenter Jon Snow described such insistence as "poppy fascism". He said he wore a poppy off air but would not wear one or any symbol -- such as an AIDS ribbon -- while broadcasting.

Guardian columnist Marina Hyde described the outrage of the Mail and other media commentators as "phoney poppy apoplexy".

"The point so often ignored is that the second world war, in particular, was fought to allow people the choice in this and many other matters," she wrote. "Victory meant freedom from fascism, which makes Jon Snow's choice of words for this annual hounding of any public figure pictured without one – "poppy fascism" – particularly significant."

The Royal British Legion which runs the Poppy Appeal itself says that wearing a poppy was a voluntary gesture. But with British troops fighting, and signficant numbers dying or being wounded in Afghanistan, many argue that it is more important than ever to show the soldiers have the support of the public -- and the best way is by wearing a poppy.

On Thursday night, BNP leader Nick Griffin will appear on the BBC's leading current affairs programme "Question Time", an appearance that has provoked much anger and debate.

Griffin is no stranger to the airwaves or TV screens, regularly appearing this week alone after four leading former generals attacked his party for using military imagery as part of its campaigning

But to some politicians, including Home Secretary Alan Johnson and Cabinet minister Peter Hain, the BBC's decision to allow him on Question Time was totally wrong, giving a much higher profile platform to Griffin and his far-right views.

They also say that a recent court decision to order the BNP to open up its membership to non-whites meant the party broke race relations laws and was therefore unlawful.

One academic has said that a similar TV appearance by French far-right leader Jean-Marie Le Pen in the 1980s led to a huge increase in support for his Front National party, generating concern that Question Time will do the same for Griffin.

There is no doubt that support for the far-right is growing in Britain at the moment, although it remains very much at the fringes of mainstream politics. The BNP has dozens of councillors across the country, a seat in the London Assembly and most notably won two seats in European Parliamentary elections earlier this year.

BBC bosses argue that for that reason it is only right that Griffin is invited onto the flagship politcal show to answer questions about his party. They say it is for parliament and not for the broadcaster to censor political parties.

However former London mayor Ken Livingstone has warned that the BBC would bear moral responsibility for any rise in racial attacks, saying the presence of the BNP always led to a rise in such incidents.

Community relations experts have also expressed fear about the impact a rising far-right will have, especially in the run-up to what is predicted to be a tense election. However many say that trying to muzzle the BNP was counter-productive, and that the group should be challenged head on.

"I think we've got to have a more sophisticated approach to the far right where we do use reasoned arguments to defeat them because there's no doubt in my mind that those reasoned arguments will work," said Ted Cantle, who led the government's review into the 2001 race riots for which the far-right was held partly responsible.

"I do feel they have to be taken on and defeated in the public eye. For the most part, their arguments are completely ridiculous and people have to see them for what they are," he told Reuters. He said the unwelcome truth for mainstream politicians was that there was a "grain of truth" in some of the things the BNP said, and censoring them gave the impression this was being covered up.

However the Unite Against Fascism group said the BNP should not be treated like any ordinary political party because its views were racist (it campaigns for a halt to immigration, voluntary repatriation of immigrants and Britain's withdrawal from the European Union).

"Griffin isn't interested in impressing people with his arguments - he just wants to build the BNP by using Question Time as a platform to whip up race hatred and bigotry," the group says.

Griffin himself says the "hysterical" furore over his appearance has already been a shot in the arm to his party. "I thank the political class and their allies for being so stupid," he told the Times. "Thank you, Auntie."

Reuters UK will be live blogging Griffin's appearance on Question Time at 22.35 BST.
