Members of the public are able to visit Parliament throughout the year apart from Christmas. I would love the chance to welcome you to Westminster if you are on a visit. If you have booked onto a tour or are visiting then please do drop me an email at firstname.lastname@example.org and I would be delighted to meet you.
There are a number of things you can do when visiting Westminster, including going on a guided tour, watching committees and watching debates in the House of Commons - including coming to watch Prime Minister's Questions although you will need tickets for PMQ's as it is the most popular event of the week.
If you would like to attend Parliament you can visit the link - Visit - UK Parliament. Here you can book tickets and arrange to have tours of the Palace of Westminster.
