Iran is offering to end its chokehold on the Strait of Hormuz without addressing its nuclear programme, two regional officials with knowledge of the proposal said on Monday.

Iran also wants the United States to end its blockade of the country as part of its proposal, according to the two officials, who spoke on condition of anonymity to discuss the closed-door negotiations.

The new proposal, passed on to the US by Pakistan, is not likely to receive the backing of US President Donald Trump, who wants to end Iran's atomic programme as part of an overall deal including the Strait of Hormuz to make the ceasefire permanent.
