standard visa for working as a consultant contract

Hello,

How are you, every one ?

I have to ask something about work under a short-term (3 months) consultant contract in UK, while with 6 months' standard visitor visa. I came to UK for tourist visit, while before I want to go back to France, I got a short-term consultant contract from UK.

1: My standard visitor visa is valid until June 2019,
2: I arrived earlier than the starting date of my consultant contract, for example, I arrived at 30 January, while the 3 months' consultant contract start from 2 February?

Do I have to stop my UK visit, (I have booked room, car, etc) and go back to France to advance the consultant contract ?
Or Can I stay in UK to finish the consultant contract in 3 months?
Or Can I stay in UK to advance the consultant contract in minimum one month , less than 30 days?

Thank you
Qiao

You are NOT permitted to do ANY form of work (contract, full time, part time, paid or unpaid) while in the UK on a visitor visa. It is a breach of your visa conditions.

Hi, Thank you for your response. Got it. Thank you.

And I think this rule applies in every country.
