Mixer Tap leaking and will only sometimes turn on

[Rob27]

Hi,
Please could someone give me some advice?

I have a mixer tap in the kitchen. The hot tap turns on and works perfectly fine. It is the type of tap with the cross handles that you twist to put on.

The cold tap handle turns freely as it should but I have to turn it on and off sometimes once and sometimes 10 times for it to start running.

When the water does not come out of the cold tap the handle feels very loose but when it does come out the handle does then not feel feels normal and as it should.

Also there is a leak coming from only this coldwater side where the main tap body and the valve cover (i think its called this) meet.

Please could anyone advise me how to fix it? as I'm no plumber.
