Too many Tory MPs act like it’s an annoying, inconvenient part-time gig
To be a MP, is the personal choice of each MP, so if they were not willing to commit 100% why did they decide to stand in the first place.
They are technically employed by their constituents and it is to them that the MPs should be answerable to, not their party and not some second or more jobs.
It appears that some MPs have the wrong impression of what a MP is, for it is a full-time job and if done properly should not allow time for a commitment, no matter how large. However, some MPs do have very important second jobs, such as, doctors, etc and perhaps allowances should be made for such jobs, but not where the second job leads to having to leave the UK, as how can constituent’s interests be dealt with and respected say, from the Caribbean.
