Theresa May faces ministers for the first time since quitting

Prime Minister Theresa May appears to have the weight of the world off her shoulders as she faces her cabinet for the first time since quitting as Tory leader.

Today's cabinet is likely to be awkward with the outgoing PM now in a caretaker as her MPs fight a full-throttle battle to replace her at the end of July. 

But one Tory MP told MailOnline they had never seen Mrs May smiling so much since she resigned last Friday.

He said: ‘She is going. It’s like Cameron – he was 10 years younger when he walked out of the door.’

Mrs May wants to push through changes that will protect more people from modern slavery and will present it to ministers this morning.  

Leadership hopefuls Rory Stewart, Jeremy Hunt, Sajid Javid and Michael Gove all looked jovial when walking up Downing Street.

Their boss will today announce plans to create a new transparency registry to alert consumers to companies that exploit forced labour. 

Mrs May, who stepped down as leader of the governing Conservative Party earlier this month, is also due to call on world leaders to face up to their 'moral duty' and take action to halt modern slavery.

Chancellor Philip Hammond has already tried to block Mrs May’s plans for a multi-billion pound spending spree to secure her legacy.

The PM had planned to announce a series of spending pledges, including billions for schools and colleges, but has been blocked by her Chancellor.

In her final days in power, Mrs May has clashed with Mr Hammond, who is refusing to fund the pledges she wants to make, whose cost is estimated by the Treasury at £10 billion.

Mr Hammond is understood to want to keep the money aside as part of his Brexit war chest he has built up while a no-deal Brexit remains a possibility, the FT reported.
