Iran nuclear talks: how the anticipated deal shapes up

So how does the proposed deal stack up?

• The agreement runs to 80 pages in English and 100 in Farsi plus five technical annexes.
• After the announcement in Vienna, the US Congress must approve. This could take three months. If they don’t agree, President Obama may use a veto to push the deal through.
• A UN Security Council resolution will be tabled, allowing for lifting of sanctions against Iran.
• Inspectors from the International Atomic Energy Agency will verify that Iran has limited uranium enrichment and curtail agreed facilities.
• Sanctions will then be lifted, probably towards the end of the year.
• The IAEA will continue to inspect Iran’s nuclear facilities.
