Wales' newest politicians have started work following their victories in a double by-election last week.
Dai Davies arrives with his wife at the Commons on Tuesday
Trish Law has taken the Blaenau Gwent seat in the assembly and Dai Davies the constituency's seat in parliament.
Mrs Law will sit in her late husband Peter's place in the assembly chamber. Her victory stopped Labour regaining a majority in Cardiff Bay.
Mr Davies has arrived in Westminster, but expects to wait weeks before he delivers his Commons maiden speech.
He took his seat in the House of Commons on Tuesday afternoon and was sworn in as an MP amid heckling and laughter from the Labour benches and cheers from the opposition.
When Speaker Michael Martin shook Mr Davies' hand and told him to enjoy his time in parliament, one Labour MP called out "enjoy it while you can".
Trish Law will sit in her late husband's place in the Senedd
Mr Davies took the oath of allegiance to the Queen and signed the roll of the House.
Mr Davies said he and Mrs Law will probably share the same constituency office in Blaenau Gwent, at least for the run up to next year's assembly elections.
He said it was a way for the two independents - both were backed by the Blaenau Gwent People's Voice group - to save money and continue their links to the community.
The Blaenau Gwent by-elections were called following the death of Mrs Law's husband, Peter Law, in April this year.
Mr Law left Labour in protest last year over the party's use of all-women shortlists to pick its parliamentary candidate.
He stood for Westminster as an independent at the general election, and became the area's MP, as well as representing it in the assembly.
Mrs Law was welcomed on the steps of the Senedd, the assembly's debating chamber, by the assembly's Presiding Officer Dafydd Elis Thomas.
Mr Davies, who was Mr Law's parliamentary election agent, said he expects to work from the same office as Mr Law at the Commons.
He said: "I have been to Parliament over the past 12 months, as a researcher. To enter Parliament as a Member of Parliament - it's a humbling feeling."
