May getting ready to pass the baton
Today Theresa May will take her final Prime Minister's Questions in the Commons before formally resigning as PM.
She is expected to return to Downing Street after her last appearance at the despatch box to have lunch and address Number 10 staff.
Mrs May, will then make a short statement to media waiting in the street outside the famous black door before heading to Buckingham Palace to offer her resignation to the Queen.
The monarch will then meet Boris Johnson at the Palace and invite him to form a new government.
Traditionally, the new Prime Minister makes a statement in Downing Street before stepping into Number 10 for the first time as PM.
Tomorrow, Mr Johnson is likely to spend his first full day in office finalising his Government, with appointments to the Cabinet and ministerial team - including a probable new Northern Ireland Secretary - expected.
The Commons will then rise for the summer recess, with MPs not due to return until September 3.
