Petition Asylum seekers/illegal immigrants convicted of a criminal offence in the UK should be deported

The United Kingdom has become a safe haven for a whole host of people (asylum seekers / illegal immigrants / political refugees) whole come to this country to avoid the turmoil and troubles in their home lands.
At present we habour these individuals and indeed, at the expense of the taxpayer, we provide for most of them and their families.

I propose that any one of the above people, upon conviction of any criminal offence against the state or persons living here should automatically forfeit the right to be in this country.
A criminal conviction would prove a complete disregard for the laws and rights of the inhabitants of the UK and upon conviction at court a judge should issue an order requiring their immediate deportation from this country, without any consideration for their human rights and should reject any future applications from that person should they try to gain entry to the country in future.
