Flood the Channel Tunnel. Ban cats from going outdoors. Bring back fish and chips wrapped in newspaper.

These are three demands - all rejected - from users of the government's e-petitions service.

Petitions gaining more than 100,000 signatures can be considered for a debate in parliament.

While some petitions - like Jamie Oliver's petition to tax sugary drinks - can make it all the way into law, others aren't quite so successful.

But what the Petitions Committee gives to Jamie Oliver, it takes away from may others, rejecting petitions that fall foul of its standards - set out in full here.

Here's a quick run through some of the most common reasons petitions never make it:

The petition, which attracted a flood of signatures after June's Brexit vote, was debated in September, but there's been no sign of another referendum.

Another petition that gained widespread attention was a call for parliament to ban Republican presidential candidate Donald Trump from entering the UK.

It was debated in January 2016. Mr Trump remains free to visit Britain.
