The AUKUS pact was announced on Wednesday and will show Britain's readiness to be "hard-headed" in defence of its interests. The Prime Minister’s trip is expected to be largely environmentally-focused where he will urge world leaders to take greater action on their commitments to tackle the climate crisis. But the leaders are also expected to thrash out the growing row over the hated Northern Ireland Protocol, with Mr Biden voicing concerns for the integrity of the Good Friday Agreement.
With some 100 world leaders expected in New York at the United Nations General Assembly this week, Mr Johnson will seek to galvanise climate action during a series of high-level meetings.
Mr Johnson sees the annual UN meeting as a ripe opportunity to impress on major polluters the need to meet their commitments as he prepares to host the Cop26 summit in Glasgow in November.
He will also make what will be his first visit to the White House since Mr Biden succeeded Donald Trump as US president.
The Prime Minister is also likely to push for a restoration of UK-US travel, with Mr Biden's administration having imposed a ban due to soaring rates of the Delta variant of coronavirus.
8am update: Pounds and ounces could return after EU red tape bonfire
Shops could soon be allowed to sell fruit and vegetables in pounds and ounces again thanks to the scrapping of EU rules.
Ministers have announced an overhaul of all the EU laws that were kept on after the UK left the bloc.
Any leftover legislation made in Brussels will be "improved or repealed" if it is judged not to benefit the British people.
Meanwhile, New Foreign Secretary Liz Truss has launched a strong defence of the UK's security pact with the US and Australia amid a deepening diplomatic row with France.
The deal has infuriated Paris after the Australians announced they were pulling out of a £30billion agreement with the French to supply it with less-capable conventionally-powered diesel-electric vessels.
Writing in The Sunday Telegraph, Ms Truss, who was the big winner in Boris Johnson's Cabinet reshuffle, made no mention of the diplomatic stand-off with the French.
Earlier, however, a French minister scornfully referred to the UK as the "junior partner" in the trilateral agreement - known as Aukus- and accused it of returning to hide in the "American lap".
In her article, Ms Truss said the agreement, widely seen as a counter to increasing Chinese military assertiveness in the region, underlined the UK's commitment to the Indo-Pacific.
