The United Kingdom's new Brexit secretary was headed to Brussels on Thursday to hold his first talks with the European Union's chief negotiator since he took office.

The trip was Dominic Raab's first since he took on the role last week following the resignation of his predecessor David Davis over disagreements with the government over its approach to leaving the EU.

"Time to intensify our negotiations," Raab tweeted ahead of traveling to Belgium to meet Michel Barnier.

Barnier's team was analyzing the future commercial and customs relationship between the UK and EU set out in a White Paper by the British government on July 12.

The plan, known as the Chequers deal because it was there that the government hammered out the details, triggered Davis' resignation as well as that of the former foreign secretary, Boris Johnson.

Despite the turbulence, Prime Minister Theresa May managed to move forward with her plan and fend off the possibility of a no-confidence vote being lodged against her.
