Is it the EHRC or the Observer that's telling fibs?

In today's Observer I read 'Tories in new race row over identity checks for elections.' The article tells us that a leaked letter from the Equality and Human Rights Commission to Cabinet Office minister David Liddington raises concerns that identity checks to vote will deter immigrants and others from participating in the democratic process. Jeremy Corbyn, of course gets his views in, using this to bash the government. But is it true?

Apparently the crux of the letter is that under new rules, being trialled in several local authorities at the 3 May local elections, 'people will be asked at polling stations to produce documents proving their identity - such as a passport or driving licence - before casting their vote.'

But here's the thing. I happen to live in one of those trial authorities (Swindon). And it's just not true that you are asked to bring a passport or driving licence. The polling card quite clearly asks you to bring... the polling card. Nothing else.

Surely either the EHRC or the Observer couldn't be trying to mislead us for political reasons?

Update - it's been pointed out to me the government website describing the trials says that both the means used in Swindon - i.e. poll card as ID - and photo ID will be tried in different locations. However, the fact remains that the newspaper article, and by implication the EHRC complaint said that Swindon was one of the elections where photo ID would be required and it's not. There was no mention in the article of the trial of using polling cards.
