MPs are able to go on foreign delegations and I was invited on many, many foreign trips after first being elected in May 2010. I did not go on any of these trips which either fell during Parliamentary sitting time and/or were at the taxpayer’s expense.
I have however gone on delegations in the years I was the MP for Northampton North. None of these trips were at the taxpayers’ expense and all of them were when Parliament was not sitting and no votes were expected.
